/**
* Native bindings to the EXT_shader_framebuffer_fetch extension.
*
* Conventional OpenGL blending provides a configurable series of operations that can be used to combine the output values from a fragment shader with the
* values already in the framebuffer. While these operations are suitable for basic image compositing, other compositing operations or operations that
* treat fragment output as something other than a color (normals, for instance) may not be expressible without multiple passes or render-to-texture
* operations.
*
* This extension provides a mechanism whereby a fragment shader may read existing framebuffer data as input. This can be used to implement compositing
* operations that would have been inconvenient or impossible with fixed-function blending. It can also be used to apply a function to the framebuffer
* color, by writing a shader which uses the existing framebuffer color as its only input.
*
* Requires {@link GLES20 GLES 2.0}.
