/**
 * Native bindings to the EXT_422_pixels extension.
 * 
 * This extension provides support for converting 422 pixels in host memory to 444 pixels as part of the pixel storage operation.
 * 
 * The pixel unpack storage operation treats a 422 pixel as a 2 element format where the first element is C (chrominance) and the second element is L
 * (luminance). Luminance is present on all pixels; a full chrominance value requires two pixels.
 * 
 * The pixel pack storage operation converts RGB to a 422 pixel defined as a 2 element format where the first element stored is C (chrominance) and the
 * second element stored is L (luminance). Luminance is present on all pixels; a full chrominance value requires two pixels.
 * 
 * Both averaging and non-averaging is supported for green and blue assignments for pack and unpack operations.
