/**
 * Native bindings to the AMD_draw_buffers_blend extension.
 * 
 * This extension builds upon the ARB_draw_buffers and EXT_draw_buffers2 extensions. In ARB_draw_buffers (part of OpenGL 2.0), separate values could be
 * written to each color buffer. This was further enhanced by EXT_draw_buffers2 by adding in the ability to enable blending and to set color write masks
 * independently per color output.
 * 
 * This extension provides the ability to set individual blend equations and blend functions for each color output.
 * 
 * Requires {@link GL20 OpenGL 2.0} and AMD_draw_buffers_blend.
