/**
 * Native bindings to the EXT_blend_func_separate extension.
 * 
 * Blending capability is extended by defining a function that allows independent setting of the RGB and alpha blend factors for blend operations that
 * require source and destination blend factors. It is not always desired that the blending used for RGB is also applied to alpha.
 * 
 * Promoted to core in {@link GL14 OpenGL 1.4}.
