/**
 * Native bindings to the NV_draw_buffers extension.
 * 
 * This extension extends OpenGL ES 2.0 to allow multiple output colors, and provides a mechanism for directing those outputs to multiple color buffers.
 * 
 * This extension serves a similar purpose to ARB_draw_buffers except that this is for OpenGL ES 2.0.
 * 
 * When OpenGL ES 3.0 is present, this extension relaxes the order restriction on color attachments to draw framebuffer objects.
