Public Member Functions
	GraphicsImpl ()=default
	Construct.
const SDL_GLContext &	GetGLContext ()
	Return the GL Context.

Private Attributes
SDL_GLContext	context_ {}
	SDL OpenGL context.
unsigned	systemFBO_ {}
	iOS/tvOS system framebuffer handle.
unsigned	activeTexture_ {}
	Active texture unit.
unsigned	enabledVertexAttributes_ {}
	Enabled vertex attributes bitmask.
unsigned	usedVertexAttributes_ {}
	Vertex attributes bitmask used by the current shader program.
unsigned	instancingVertexAttributes_ {}
	Vertex attribute instancing bitmask for keeping track of divisors.
const HashMap< Pair< unsigned char, unsigned char >, unsigned > *	vertexAttributes_ {}
	Current mapping of vertex attribute locations by semantic. The map is owned by the shader program, so care must be taken to switch a null shader program when it's destroyed.
unsigned	boundFBO_ {}
	Currently bound frame buffer object.
unsigned	boundVBO_ {}
	Currently bound vertex buffer object.
unsigned	boundUBO_ {}
	Currently bound uniform buffer object.
unsigned	resolveSrcFBO_ {}
	Read frame buffer for multisampled texture resolves.
unsigned	resolveDestFBO_ {}
	Write frame buffer for multisampled texture resolves.
int	pixelFormat_ {}
	Current pixel format.
HashMap< unsigned long long, FrameBufferObject >	frameBuffers_
	Map for FBO's per resolution and format.
unsigned	textureTypes_ [MAX_TEXTURE_UNITS] {}
	OpenGL texture types in use.
ConstantBufferMap	allConstantBuffers_
	Constant buffer search map.
ConstantBuffer *	constantBuffers_ [MAX_SHADER_PARAMETER_GROUPS *2] {}
	Currently bound constant buffers.
PODVector< ConstantBuffer * >	dirtyConstantBuffers_
	Dirty constant buffers.
unsigned	lastInstanceOffset_ {}
	Last used instance data offset.
HashMap< unsigned, SharedPtr< Texture2D > >	depthTextures_
	Map for additional depth textures, to emulate Direct3D9 ability to mix render texture and backbuffer rendering.
ShaderProgram *	shaderProgram_ {}
	Shader program in use.
ShaderProgramMap	shaderPrograms_
	Linked shader programs.
bool	fboDirty_ {}
	Need FBO commit flag.
bool	vertexBuffersDirty_ {}
	Need vertex attribute pointer update flag.
bool	sRGBWrite_ {}
	sRGB write mode flag.
