/**
 * Native bindings to the EXT_draw_buffers_indexed extension.
 * 
 * This extension builds upon the EXT_draw_buffers extension. In EXT_draw_buffers (part of OpenGL ES 3.0), separate values could be written to each color
 * buffer, but the blend enable, blend functions, blend equations and color write masks are global and apply to all color outputs.
 * 
 * This extension provides the ability to independently
 * 
 * 
 * enable or disable blending
 * set the blend equations
 * set the blend functions, and
 * set the color write masks per color output.
 * 
 * 
 * This extension introduces indexed versions of the enable, blend equation, blend function, and color mask commands, as well as associated indexed
 * queries in order to control and query these states independently on a per-color output basis.
 * 
 * Requres {@link GLES30 GLES 3.0} or {@link EXTDrawBuffers EXT_draw_buffers}.
