Introduction

Welcome to the POV-Ray for Unix version 3.7.1 documentation.

+

Welcome to the POV-Ray for Unix version 3.8 documentation.

This content is divided into three major sections. A platform specific section, a tutorial section, and a reference section. New to POV-Ray? You'd most likely want to begin with the tutorial section. Need to locate something quickly? The list of identifiers and keywords is a good place to start. See the changes and new features summary for what's new with this release.

Enjoy!

The Create_Ini option or +GI switch provides an easy way to create an INI file with all of the rendering options, so you can re-run files with the same options, or ensure you have all the same options when resuming. This option creates an INI file with every option set at the value used for that rendering. This includes default values which you have not specified. For example if you run POV-Ray with...

3.2.8.6 BSP Bounding

Please keep in mind that this implementation of BSP is highly beta and will not speed up scenes in many cases (and in fact may slow some down). In particular the building of the tree can take a long time and lots of memory in severe cases. Using the BSP tree rather than our traditional BVH (Bounding Volume Hierarchy) system (default or +BM1) is a choice best made for specific scenes that will benefit from the way the BSP operates, and in particular if the render is long enough to offset the build time. The BSP tree build time will be constant for a given scene and set of BSP parameters, regardless of the output resolution. A 30-second BSP build may not be a good choice on a 60-second test render but may be acceptable for a 60-minute final render if the use of BSP adds a few pixels per second.

On some scenes the difference however will be dramatic, with short build times and radically increased render speed.

We have provided some BSP-related options via the INI file and encourage you to experiment with them to see if you can get better results than the default values built in to POV-Ray. We will listen to feedback from this and if necessary tweak the defaults.

Note: POV-Ray is a command-line program on Unix and other text-based operating systems and is menu-driven on Windows and Macintosh platforms. Some of these operating systems use folders to store files while others use directories. Some separate the folders and sub-folders with a slash character (/), back-slash character (\), or others. 

-
We have tried to make this documentation as generic as possible but sometimes we have to refer to folders, files, options etc. and there is noway to escape it. Here are some assumptions we make...
  1.  You installed POV-Ray in the C:\POVRAY36 directory. For MS-Dos this is probably true but for Unix it might be /usr/povray3, or for Windows it might be C:\Program Files\POV-Ray for Windows v3.6, for Mac it might be MyHD:Apps:POV-Ray 36:, or you may have used some other drive or directory. So if we tell you that Include files are stored in the \povray36\include directory, we assume you can translate that to something like::POVRAY36:INCLUDE or C:\Program Files\POV-Ray for Windows v3.6\include or whatever is appropriate for your platform, operating system and installation.
  2.  POV-Ray uses INI files and/or command-line switches (if available) to choose options in all versions, but Windows and Mac also use dialog boxes or menu choices to set options. We will describe options assuming you are using switches or INI files when describing what the options do. We have taken care to use the same terminology in designing menus and dialogs as we use in describing switches or INI keywords. See your version-specific documentation on menu and dialogs.
  3.  Some of you are reading this using a help-reader, built-in help,web-browser, formatted printout, or plain text file. We assume you know how to get around in which ever medium you are using. We will say See the chapter on Setting POV-Ray Options we assume you can click, scroll, browse, flip pages or whatever to get there.

+
Note: POV-Ray is available as a command-line program on some platforms and as a GUI on others. Some of these platforms use folders to store files while others use directories. Some separate the folders and sub-folders with a slash character (/), back-slash character (\), or others. We have tried to make this documentation as generic as possible but sometimes we have to refer to folders, files, options etc., and rather than try to represent all possible combinations
+we sometimes simplify the documentation by referring to a hypothetical 'standard installation' of POV-Ray upon a Microsoft Windows computer.
+

+
 Here are some additional assumptions to be found in the documentation:

+
    
+
  1. You installed POV-Ray in the default location for Windows, with the binaries in c:\Program Files\POV-Ray\vX.y and include/scene files in My Documents\POV-Ray\vX.y.
+If we say 'include files are stored in the include directory', we mean the directory called 'include' located immediately within the folder which was used for documents, in the above case, it would be My Documents\POV-Ray\vX.y\include. We assume you can translate that to something like /usr/local/share/povray/vX.y/include for Linux or whatever is appropriate for your platform, operating system and personal installation.
+
  2.  POV-Ray uses INI files and/or command-line switches (if available) to choose options in all versions, but some platforms (e.g. Windows) also use dialog boxes or menu choices to set options. We will describe options assuming you are using switches or INI files when describing what the options do, as it is consistent across all platforms (all GUI versions of POV-Ray also provide a means of accepting command-line options and reading INI files from within the GUI - generally speaking, the menus and dialogs just provide
+an easier means of doing the same thing).
+
  3. You may be reading this documentation using an operating-system specific help program, web browser, physical printout, PDF viewer, or text editor. We assume you know how to get around in which ever medium you are using. If we say "See the chapter on Setting POV-Ray Options" we assume you can click, scroll, browse, flip pages or whatever to get there.

-Most computer video modes and graphics printers use perfectly square pixels.
-For example Macintosh displays and IBM SVGA modes 640x480, 800x600 and
-1024x768 all use square pixels. When your intended viewing method uses square
-pixels then the width and height you set with the Width and

-should also have the same ratio as the up and right

    A Change in version 3.8 redefines how the right vector default is derived. Previously a fixed value, it is now a calculated value that is based on the image width and height specified at render time. As usual, the image width and height can be specified from either the pull down menu available in GUI versions ONLY or the +Wn and +Hn command-line options available to ALL versions. This behavior is conditional upon the last effective #version directive before the camera definition. The default up vector remains as <0,1,0>.
    
+
+
    To retain legacy behavior see the example below:
    
+
 
    +#version X.y; // X.y is a version less than 3.8
 camera {
   location <3,5,-10>
-  up    <0,1,0>
-  right  <1,0,0>
   look_at <0,2,1>
   }

    This specifies a perfectly square image. On a square pixel display like
-SVGA you would use pixel settings such as +W480 +H480 or 
-+W600 +H600. However on the non-square pixel Amiga 320x400 mode you
-would want to use values of +W240 +H400 to render a square
-image.
    
-
    
-The bottom line issue is this: the up and right
-vectors should specify the artist's intended aspect ratio for the image
-and the pixel settings should be adjusted to that same ratio for square
-pixels and to an adjusted pixel resolution for non-square pixels. The

    Isosurfaces can be used in CSG shapes since they are solid finite objects - if not finite by themselves, they are through the cross section with the container. By default POV-Ray searches only for the first surface which the ray intersects. However, when using an isosurface in CSG operations, the other surfaces must also be found. Consequently, the keyword max_trace followed by an integer value, must be added to the isosurface statement. To check for all surfaces, use the keyword all_intersections instead. With max_trace it only checks until that number is reached.
    Note: The current implementation has a limit of 10 intersections in all cases.

        Each Value is a float value between 0.0 and 1.0 inclusive and each  <Height, Slope> is a 2 component vector such as <0,1> where the first value represents the apparent height of the wave and the second value represents the slope of the wave at that point. The height should range between 0.0 and 1.0 but any value could be used.
        
 
        The slope value is the change in height per unit of distance. For example a slope of zero means flat, a slope of 1.0 means slope upwards at a 45 degree angle and a slope of -1 means slope down at 45 degrees. Theoretically a slope straight up would have infinite slope. In practice, slope values should be kept in the range -3.0 to +3.0. Keep in mind that this is only the visually apparent slope. A normal does not actually change the surface.
        
 
        For example here is how to make the ramp slope up for the first half and back down on the second half creating a triangle wave with a sharp peak in the center.

      Note: POV-Ray is available as a command-line program on some platforms and as a GUI on others. Some of these platforms use folders to store files while others use directories. Some separate the folders and sub-folders with a slash character (/), back-slash character (\), or others. We have tried to make this documentation as generic as possible but sometimes we have to refer to folders, files, options etc., and rather than try to represent all possible combinations
 we sometimes simplify the documentation by referring to a hypothetical 'standard installation' of POV-Ray upon a Microsoft Windows computer.
 
      
 
       Here are some additional assumptions to be found in the documentation:
      
 
        
-
      1. You installed POV-Ray in the default location (on Windows, binaries in c:\Program Files\POV-Ray\v3.7 and include/scene files in My Documents\POV-Ray\v3.7).
-If we say 'include files are stored in the include directory', we mean the directory called 'include' located immediately within the folder which was used for documents (in the above case, it would be My Documents\POV-Ray\v3.7\include). We assume you can translate that to something like /usr/local/share/povray-3.7/include (for Linux) or whatever is appropriate for your platform, operating system and personal installation.
+
      2. You installed POV-Ray in the default location for Windows, with the binaries in c:\Program Files\POV-Ray\vX.y and include/scene files in My Documents\POV-Ray\vX.y.
+If we say 'include files are stored in the include directory', we mean the directory called 'include' located immediately within the folder which was used for documents, in the above case, it would be My Documents\POV-Ray\vX.y\include. We assume you can translate that to something like /usr/local/share/povray/vX.y/include for Linux or whatever is appropriate for your platform, operating system and personal installation.
 
      3.  POV-Ray uses INI files and/or command-line switches (if available) to choose options in all versions, but some platforms (e.g. Windows) also use dialog boxes or menu choices to set options. We will describe options assuming you are using switches or INI files when describing what the options do, as it is consistent across all platforms (all GUI versions of POV-Ray also provide a means of accepting command-line options and reading INI files from within the GUI - generally speaking, the menus and dialogs just provide
 an easier means of doing the same thing).
 
      4. You may be reading this documentation using an operating-system specific help program, web browser, physical printout, PDF viewer, or text editor. We assume you know how to get around in which ever medium you are using. If we say "See the chapter on Setting POV-Ray Options" we assume you can click, scroll, browse, flip pages or whatever to get there.

+		Using SDL with Microsoft Visual C++
+	
+	
+		
    
+			Using SDL with Microsoft Visual C++
+		
    
+		
    
+			by Lion Kimbro and additions by 
+				James Turk
+		
    
+		
    
+			You can either use the precompiled libraries from  the SDL Download web site , or you can build SDL yourself.
+		
    
+		
    
+			Building SDL
+		
    
+		
    
+			Go into the VisualC directory and double-click on the Visual Studio solution for your version of Visual Studio, e.g. SDL_VS2008.sln This should open up the IDE.
+		
    
+		
    
+			There are different solution files for the various
+			versions of the IDE. Please use the appropriate version
+			2008, 2010, 2012 or 2013.
+		
    
+		
    
+			Build the .dll and .lib files.
+		
    
+		
    
+			This is done by right clicking on each project in turn (Projects are listed in 
+			the Workspace panel in the FileView tab), and selecting "Build".
+		
    
+		
    
+			You may get a few warnings, but you should not get any errors. You do have to 
+			have at least the DirectX 9 SDK installed, however. The latest 
+			version of DirectX can be downloaded from Microsoft.
+		
    
+		
    
+			Later, we will refer to the following .lib and .dll files that have just been 
+			generated:
+		
    
+		
      
+    
    •  SDL2.dll
      • 
+    
    •  SDL2.lib
      • 
+    
    •  SDL2main.lib
      • 
+    
    
+		
    
+			Search for these using the Windows Find (Windows-F) utility inside the VisualC directory.
+		
    
+		
    
+			Creating a Project with SDL
+		
    
+		
    
+			Create a project as a Win32 Application.
+		
    
+		
    
+			Create a C++ file for your project.
+		
    
+		
    
+			Set the C runtime to "Multi-threaded DLL" in the menu: Project|Settings|C/C++ 
+				tab|Code Generation|Runtime Library .
+		
    
+		
    
+			Add the SDL include directory to your list of includes in the 
+			menu: Project|Settings|C/C++ tab|Preprocessor|Additional include directories 
+			.
+			
    
+			VC7 Specific: Instead of doing this I find it easier to 
+					add the include and library directories to the list that VC7 keeps. Do this by 
+					selecting Tools|Options|Projects|VC++ Directories and under the "Show 
+					Directories For:" dropbox select "Include Files", and click the "New Directory 
+					Icon" and add the [SDLROOT]\include directory (e.g. If you installed to 
+					c:\SDL\ add c:\SDL\include). Proceed to change the 
+					dropbox selection to "Library Files" and add [SDLROOT]\lib.
+		
    
+			
    
+				The "include directory" I am referring to is the include folder 
+				within the main SDL directory (the one that this HTML file located within).
+			
    
+			
    
+				Now we're going to use the files that we had created earlier in the Build SDL 
+				step.
+			
    
+			
    
+				Copy the following files into your Project directory:
+			
    
+			
      
+     
    •  SDL2.dll
      • 
+     
    
+			
    
+				Add the following files to your project (It is not necessary to copy them to 
+				your project directory):
+			
    
+			
      
+     
    •  SDL2.lib 
      • 
+     
    •  SDL2main.lib
      • 
+     
    
+			
    
+				(To add them to your project, right click on your project, and select "Add 
+				files to project")
+			
    
+		
    Instead of adding the files to your project it is more 
+					desirable to add them to the linker options: Project|Properties|Linker|Command 
+					Line and type the names of the libraries to link with in the "Additional 
+					Options:" box.  Note: This must be done for each build 
+					configuration (e.g. Release,Debug).
    
+		
    
+			SDL 101, First Day of Class
+		
    
+		
    
+			Now create the basic body of your project. The body of your program should take 
+			the following form:
+			
    
+#include "SDL.h"
+
+int main( int argc, char* argv[] )
+{
+  // Body of the program goes here.
+  return 0;
+}
+			
    
+		
    
+		
    
+			That's it!
+		
    
+		
    
+			I hope that this document has helped you get through the most difficult part of 
+			using the SDL: installing it. Suggestions for improvements to this document 
+			should be sent to the writers of this document.
+		
    
+		
    
+			Thanks to Paulus Esterhazy (pesterhazy@gmx.net), for the work on VC++ port.

+			This document was originally called "VisualC.txt", and was written by 
+				Sam Lantinga.
+		
    
+		
    
+			Later, it was converted to HTML and expanded into the document that you see 
+			today by Lion Kimbro.
+		
    
+		
    Minor Fixes and Visual C++ 7 Information (In Green) was added by James Turk

+
+This is a list of major changes in SDL's version history.
+
+---------------------------------------------------------------------------
+2.0.5:
+---------------------------------------------------------------------------
+
+General:
+* Implemented audio capture support for some platforms
+* Added SDL_DequeueAudio() to retrieve audio when buffer queuing is turned on for audio capture
+* Added events for dragging and dropping text
+* Added events for dragging and dropping multiple items
+* By default the click raising a window will not be delivered to the SDL application. You can set the hint SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH to "1" to allow that click through to the window.
+* Saving a surface with an alpha channel as a BMP will use a newer BMP format that supports alpha information. You can set the hint SDL_HINT_BMP_SAVE_LEGACY_FORMAT to "1" to use the old format.
+* Added SDL_GetHintBoolean() to get the boolean value of a hint
+* Added SDL_RenderSetIntegerScale() to set whether to smoothly scale or use integral multiples of the viewport size when scaling the rendering output
+* Added SDL_CreateRGBSurfaceWithFormat() and SDL_CreateRGBSurfaceWithFormatFrom() to create an SDL surface with a specific pixel format
+* Added SDL_GetDisplayUsableBounds() which returns the area usable for windows. For example, on Mac OS X, this subtracts the area occupied by the menu bar and dock.
+* Added SDL_GetWindowBordersSize() which returns the size of the window's borders around the client area
+* Added a window event SDL_WINDOWEVENT_HIT_TEST when a window had a hit test that wasn't SDL_HITTEST_NORMAL (e.g. in the title bar or window frame)
+* Added SDL_SetWindowResizable() to change whether a window is resizable
+* Added SDL_SetWindowOpacity() and SDL_GetWindowOpacity() to affect the window transparency
+* Added SDL_SetWindowModalFor() to set a window as modal for another window
+* Added support for AUDIO_U16LSB and AUDIO_U16MSB to SDL_MixAudioFormat()
+* Fixed flipped images when reading back from target textures when using the OpenGL renderer
+* Fixed texture color modulation with SDL_BLENDMODE_NONE when using the OpenGL renderer
+* Fixed bug where the alpha value of colorkeys was ignored when blitting in some cases
+
+Windows:
+* Added a hint SDL_HINT_WINDOWS_DISABLE_THREAD_NAMING to prevent SDL from raising a debugger exception to name threads. This exception can cause problems with .NET applications when running under a debugger.
+* The hint SDL_HINT_THREAD_STACK_SIZE is now supported on Windows
+* Fixed XBox controller triggers automatically being pulled at startup
+* The first icon from the executable is used as the default window icon at runtime
+* Fixed SDL log messages being printed twice if SDL was built with C library support
+* Reset dead keys when the SDL window loses focus, so dead keys pressed in SDL applications don't affect text input into other applications.
+
+Mac OS X:
+* Fixed selecting the dummy video driver
+* The caps lock key now generates a pressed event when pressed and a released event when released, instead of a press/release event pair when pressed.
+* Fixed mouse wheel events on Mac OS X 10.12
+* The audio driver has been updated to use AVFoundation for better compatibility with newer versions of Mac OS X
+
+Linux:
+* Added support for the Fcitx IME
+* Added a window event SDL_WINDOWEVENT_TAKE_FOCUS when a window manager asks the SDL window whether it wants to take focus.
+* Refresh rates are now rounded instead of truncated, e.g. 59.94 Hz is rounded up to 60 Hz instead of 59.
+* Added initial support for touchscreens on Raspberry Pi
+
+OpenBSD:
+* SDL_GetBasePath() is now implemented on OpenBSD
+
+iOS:
+* Added support for dynamically loaded objects on iOS 8 and newer
+
+tvOS:
+* Added support for Apple TV
+* Added a hint SDL_HINT_APPLE_TV_REMOTE_ALLOW_ROTATION to control whether he Apple TV remote's joystick axes will automatically match the rotation of the remote.  
+
+Android:
+* Fixed SDL not resizing window when Android screen resolution changes
+* Corrected the joystick Z axis reporting for the accelerometer
+

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+* Please submit changes by sending them to the public Khronos Bugzilla

+*    http://www.khronos.org/registry/implementers_guide.pdf
+*
+* This file should be included as
+*        #include 
+* by Khronos client API header files that use its types and defines.
+*
+* The types in khrplatform.h should only be used to define API-specific types.
+*
+* Types defined in khrplatform.h:
+*    khronos_int8_t              signed   8  bit
+*    khronos_uint8_t             unsigned 8  bit
+*    khronos_int16_t             signed   16 bit
+*    khronos_uint16_t            unsigned 16 bit
+*    khronos_int32_t             signed   32 bit
+*    khronos_uint32_t            unsigned 32 bit
+*    khronos_int64_t             signed   64 bit
+*    khronos_uint64_t            unsigned 64 bit
+*    khronos_intptr_t            signed   same number of bits as a pointer
+*    khronos_uintptr_t           unsigned same number of bits as a pointer
+*    khronos_ssize_t             signed   size
+*    khronos_usize_t             unsigned size
+*    khronos_float_t             signed   32 bit floating point
+*    khronos_time_ns_t           unsigned 64 bit time in nanoseconds
+*    khronos_utime_nanoseconds_t unsigned time interval or absolute time in
+*                                         nanoseconds
+*    khronos_stime_nanoseconds_t signed time interval in nanoseconds
+*    khronos_boolean_enum_t      enumerated boolean type. This should
+*      only be used as a base type when a client API's boolean type is
+*      an enum. Client APIs which use an integer or other type for
+*      booleans cannot use this as the base type for their boolean.
+*
+* Tokens defined in khrplatform.h:
+*
+*    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
+*
+*    KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
+*    KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.

+ *  \file SDL_haptic.h
+ *
+ *  \brief The SDL Haptic subsystem allows you to control haptic (force feedback)
+ *         devices.
+ *
+ *  The basic usage is as follows:
+ *   - Initialize the Subsystem (::SDL_INIT_HAPTIC).
+ *   - Open a Haptic Device.
+ *    - SDL_HapticOpen() to open from index.
+ *    - SDL_HapticOpenFromJoystick() to open from an existing joystick.
+ *   - Create an effect (::SDL_HapticEffect).
+ *   - Upload the effect with SDL_HapticNewEffect().
+ *   - Run the effect with SDL_HapticRunEffect().
+ *   - (optional) Free the effect with SDL_HapticDestroyEffect().
+ *   - Close the haptic device with SDL_HapticClose().
+ *
+ * \par Simple rumble example:
+ * \code
+ *    SDL_Haptic *haptic;
+ *
+ *    // Open the device
+ *    haptic = SDL_HapticOpen( 0 );
+ *    if (haptic == NULL)
+ *       return -1;
+ *
+ *    // Initialize simple rumble
+ *    if (SDL_HapticRumbleInit( haptic ) != 0)
+ *       return -1;
+ *
+ *    // Play effect at 50% strength for 2 seconds
+ *    if (SDL_HapticRumblePlay( haptic, 0.5, 2000 ) != 0)
+ *       return -1;
+ *    SDL_Delay( 2000 );
+ *
+ *    // Clean up
+ *    SDL_HapticClose( haptic );
+ * \endcode
+ *
+ * \par Complete example:
+ * \code
+ * int test_haptic( SDL_Joystick * joystick ) {
+ *    SDL_Haptic *haptic;
+ *    SDL_HapticEffect effect;
+ *    int effect_id;
+ *
+ *    // Open the device
+ *    haptic = SDL_HapticOpenFromJoystick( joystick );
+ *    if (haptic == NULL) return -1; // Most likely joystick isn't haptic
+ *
+ *    // See if it can do sine waves
+ *    if ((SDL_HapticQuery(haptic) & SDL_HAPTIC_SINE)==0) {
+ *       SDL_HapticClose(haptic); // No sine effect
+ *       return -1;
+ *    }
+ *
+ *    // Create the effect
+ *    memset( &effect, 0, sizeof(SDL_HapticEffect) ); // 0 is safe default
+ *    effect.type = SDL_HAPTIC_SINE;
+ *    effect.periodic.direction.type = SDL_HAPTIC_POLAR; // Polar coordinates
+ *    effect.periodic.direction.dir[0] = 18000; // Force comes from south
+ *    effect.periodic.period = 1000; // 1000 ms
+ *    effect.periodic.magnitude = 20000; // 20000/32767 strength
+ *    effect.periodic.length = 5000; // 5 seconds long
+ *    effect.periodic.attack_length = 1000; // Takes 1 second to get max strength
+ *    effect.periodic.fade_length = 1000; // Takes 1 second to fade away
+ *
+ *    // Upload the effect
+ *    effect_id = SDL_HapticNewEffect( haptic, &effect );
+ *
+ *    // Test the effect
+ *    SDL_HapticRunEffect( haptic, effect_id, 1 );
+ *    SDL_Delay( 5000); // Wait for the effect to finish
+ *
+ *    // We destroy the effect, although closing the device also does this
+ *    SDL_HapticDestroyEffect( haptic, effect_id );
+ *
+ *    // Close the device
+ *    SDL_HapticClose(haptic);
+ *
+ *    return 0; // Success

+ *  If type is ::SDL_HAPTIC_POLAR, direction is encoded by hundredths of a
+ *  degree starting north and turning clockwise.  ::SDL_HAPTIC_POLAR only uses

+ *   - North: 0 (0 degrees)
+ *   - East: 9000 (90 degrees)
+ *   - South: 18000 (180 degrees)
+ *   - West: 27000 (270 degrees)
+ *
+ *  If type is ::SDL_HAPTIC_CARTESIAN, direction is encoded by three positions
+ *  (X axis, Y axis and Z axis (with 3 axes)).  ::SDL_HAPTIC_CARTESIAN uses
+ *  the first three \c dir parameters.  The cardinal directions would be:
+ *   - North:  0,-1, 0
+ *   - East:   1, 0, 0
+ *   - South:  0, 1, 0
+ *   - West:  -1, 0, 0
+ *
+ *  The Z axis represents the height of the effect if supported, otherwise
+ *  it's unused.  In cartesian encoding (1, 2) would be the same as (2, 4), you
+ *  can use any multiple you want, only the direction matters.
+ *
+ *  If type is ::SDL_HAPTIC_SPHERICAL, direction is encoded by two rotations.
+ *  The first two \c dir parameters are used.  The \c dir parameters are as
+ *  follows (all values are in hundredths of degrees):
+ *   - Degrees from (1, 0) rotated towards (0, 1).
+ *   - Degrees towards (0, 0, 1) (device needs at least 3 axes).

+ *  \brief A structure containing a template for a Periodic effect.
+ *
+ *  The struct handles the following effects:
+ *   - ::SDL_HAPTIC_SINE
+ *   - ::SDL_HAPTIC_LEFTRIGHT
+ *   - ::SDL_HAPTIC_TRIANGLE
+ *   - ::SDL_HAPTIC_SAWTOOTHUP
+ *   - ::SDL_HAPTIC_SAWTOOTHDOWN
+ *
+ *  A periodic effect consists in a wave-shaped effect that repeats itself
+ *  over time.  The type determines the shape of the wave and the parameters
+ *  determine the dimensions of the wave.
+ *
+ *  Phase is given by hundredth of a degree meaning that giving the phase a value
+ *  of 9000 will displace it 25% of its period.  Here are sample values:
+ *   -     0: No phase displacement.
+ *   -  9000: Displaced 25% of its period.
+ *   - 18000: Displaced 50% of its period.
+ *   - 27000: Displaced 75% of its period.
+ *   - 36000: Displaced 100% of its period, same as 0, but 0 is preferred.

+ *  You can also pass ::SDL_HAPTIC_INFINITY to length instead of a 0-32767

+ *
+ *  Additionally, the ::SDL_HAPTIC_RAMP effect does not support a duration of
+ *  ::SDL_HAPTIC_INFINITY.
+ *
+ *  Button triggers may not be supported on all devices, it is advised to not

+ *  the joystick.
+ *
+ *  If both attack_length and fade_level are 0, the envelope is not used,
+ *  otherwise both values are used.
+ *
+ *  Common parts:
+ *  \code
+ *  // Replay - All effects have this
+ *  Uint32 length;        // Duration of effect (ms).
+ *  Uint16 delay;         // Delay before starting effect.
+ *
+ *  // Trigger - All effects have this
+ *  Uint16 button;        // Button that triggers effect.
+ *  Uint16 interval;      // How soon before effect can be triggered again.
+ *
+ *  // Envelope - All effects except condition effects have this
+ *  Uint16 attack_length; // Duration of the attack (ms).
+ *  Uint16 attack_level;  // Level at the start of the attack.

+/** \brief Allows back-button-press events on Windows Phone to be marked as handled
+ *
+ *  Windows Phone devices typically feature a Back button.  When pressed,
+ *  the OS will emit back-button-press events, which apps are expected to
+ *  handle in an appropriate manner.  If apps do not explicitly mark these
+ *  events as 'Handled', then the OS will invoke its default behavior for
+ *  unhandled back-button-press events, which on Windows Phone 8 and 8.1 is to
+ *  terminate the app (and attempt to switch to the previous app, or to the
+ *  device's home screen).
+ *
+ *  Setting the SDL_HINT_WINRT_HANDLE_BACK_BUTTON hint to "1" will cause SDL
+ *  to mark back-button-press events as Handled, if and when one is sent to
+ *  the app.
+ *
+ *  Internally, Windows Phone sends back button events as parameters to
+ *  special back-button-press callback functions.  Apps that need to respond
+ *  to back-button-press events are expected to register one or more
+ *  callback functions for such, shortly after being launched (during the
+ *  app's initialization phase).  After the back button is pressed, the OS
+ *  will invoke these callbacks.  If the app's callback(s) do not explicitly
+ *  mark the event as handled by the time they return, or if the app never
+ *  registers one of these callback, the OS will consider the event
+ *  un-handled, and it will apply its default back button behavior (terminate
+ *  the app).
+ *
+ *  SDL registers its own back-button-press callback with the Windows Phone
+ *  OS.  This callback will emit a pair of SDL key-press events (SDL_KEYDOWN
+ *  and SDL_KEYUP), each with a scancode of SDL_SCANCODE_AC_BACK, after which
+ *  it will check the contents of the hint, SDL_HINT_WINRT_HANDLE_BACK_BUTTON.
+ *  If the hint's value is set to "1", the back button event's Handled
+ *  property will get set to 'true'.  If the hint's value is set to something
+ *  else, or if it is unset, SDL will leave the event's Handled property
+ *  alone.  (By default, the OS sets this property to 'false', to note.)
+ *
+ *  SDL apps can either set SDL_HINT_WINRT_HANDLE_BACK_BUTTON well before a
+ *  back button is pressed, or can set it in direct-response to a back button
+ *  being pressed.
+ *
+ *  In order to get notified when a back button is pressed, SDL apps should
+ *  register a callback function with SDL_AddEventWatch(), and have it listen
+ *  for SDL_KEYDOWN events that have a scancode of SDL_SCANCODE_AC_BACK.
+ *  (Alternatively, SDL_KEYUP events can be listened-for.  Listening for
+ *  either event type is suitable.)  Any value of SDL_HINT_WINRT_HANDLE_BACK_BUTTON
+ *  set by such a callback, will be applied to the OS' current
+ *  back-button-press event.
+ *
+ *  More details on back button behavior in Windows Phone apps can be found
+ *  at the following page, on Microsoft's developer site:
+ *  http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj247550(v=vs.105).aspx
