BGRA	Same as RGBA but with swapped red and blue channels.
ImageExternal	Handle to single OES_EGL_image_external texture.
LumaChromaPair	Pointer to array of two GL texture handles for YpCbCr texture pair (GL_LUMINANCE, GL_LUMINANCE_ALPHA formats).

DrawTexturedBackground()

void HPS::DrawWindowEvent::DrawTexturedBackground	(	OpaqueHandle	in_texture,
		BackgroundTextureFormat	in_format,
		MatrixKit const &	in_matrix,
		IntRectangle const &	in_extent
	)		const

Function for drawing a platform-specific texture in place of the normal window background.

Parameters

in_texture	The platform-specific texture handle(s)
in_format	The format of the texture(s) provided through the 'in_texture' parameter.
in_matrix	A transformation to apply to the uv coordinates used to draw the texture to the window.
in_extent	The screen extent for the window background to be drawn.
