/**
 * Native bindings to the ARB_draw_buffers extension.
 * 
 * 
This extension extends {@link ARBFragmentProgram ARB_fragment_program} and {@link ARBFragmentShader ARB_fragment_shader} to allow multiple output colors, and provides a mechanism for
 * directing those outputs to multiple color buffers.
 * 
 * 
Requires {@link GL13 OpenGL 1.3}. Promoted to core in {@link GL20 OpenGL 2.0}.
