Subject: [PATCH] feat: window background transparency (#2373)

- Add DrawShadow property (default true) to control drawing the backdrop shadow
- DrawBackground of the window now controls if the "frame" (the background, minus the titlebar) is visible
- DrawBackground of the Titlebar node now controls if the "titlebar" image is drawn
