'''OpenGL extension SGIX.ycrcba

This module customises the behaviour of the 
OpenGL.raw.GL.SGIX.ycrcba to provide a more 
Python-friendly API

Overview (from the spec)
	
	This extension provides a method for OpenGL to read and store
	images that are defined in standard YCRCB and YCRCBA video color
	spaces.  As with the CYMK extension, conversion to RGBA takes place
	immediately following the unpack pixel store, and preceding the
	pack pixel store operations, and is only available on transfers to
	and from memory.  The algorithms that convert between YCRCB and
	RGBA are "black-box" in nature, and left undefined by the
	extension, however it is recommended that conversion comply with
	the CCIR standard. This extension specifies the format of a pixel
	rectangle independent of component subsampling. Component
	subsampling is specified using a separate extension.
	
	Two new formats are added, YCRCB_SGIX and YCRCBA_SGIX.
	
	YCRCB_SGIX is defined as a 3 component format representing the Cb,
	Y, and Cr values per pixel. YCRCBA_SGIX is defined as a 4 component
	format representing Cb, Y, Cr, and A values per pixel.
	
	As with the CMYK extension, this extension doesn't preclude the
	possibility of other higher quality conversion methods.
