a3 Ray Tracer

Notes to developers

Every file should include "Common/Core.h"
v2, v3, v4 are treated as default data types, and are not initialized to 0
Replaced math functions such as Sinf, Cosf etc are in global namespace and not in a3
Math functions for v2, v3 and v4 are made in global namespace and not in a3
Similarly m4x4 and quat are in global namespace and not in a3. To add to the fact all mathematics structs/classes/functions are in global namespace. This is intensional.
Identifiers that are internal to a system/code/file should begin with a3_ prefix and should not be present in a3 namespace. For example:

void a3_Log();

All other structs/classes/function/enums are and should be inside a3 namespace unless there's a good reason not to.
All preprocessor definations that can be used in any part of code must begin with A3 following with the defination name, should contain no space(' ') and must be all capitals. For example:

#define A3NULL 0
#define A3DEBUG

Preprocessor that are only internally used by the single part of the code and made with no intension of using it outside that scope should also begin with A3 but every word should be seperated by a underscore('_') and should all be capitals. For example:

#define A3_RENDER_MAX_COUNT 1000
#define A3_WINDOW_CLASS_NAME "WindowClassName"

All macros should begin with a3 and should be camel case with first letter being capital. For example:

#define a3Bit(n) (1 << (n))

Structs, classes, enums names should be all lower case with seperating by underscore('_'). For example:
```
struct v2;
struct font_renderer;
```
Private members should have prefix m_ and should be camel case with first letter being capital.
All functions should be "CamelCased" but if internal should have prefix a3_
All internal static identifiers should have prefix s_ and globals should have prefix g_
If globals identifiers that are to be used by other parts of the system/code should be "CamelCased"
External libraries do not have to follow these conventions but should be wrapped in our code before usage
All external libraries must be made to use our memory allocators and our libraries and not standard libraries
