'''OpenGL extension IMG.framebuffer_downsample
This module customises the behaviour of the
OpenGL.raw.GLES2.IMG.framebuffer_downsample to provide a more
Python-friendly API
Overview (from the spec)
This extension introduces the ability to attach color buffers to a
framebuffer that are at a lower resolution than the framebuffer itself, with
the GPU automatically downsampling the color attachment to fit.
This can be useful for various post-process rendering techniques where it is
desirable to generate downsampled images in an efficient manner, or for a
lower resolution post-process technique.
This extension exposes at least a 2 x 2 downscale. Other downsampling modes
may be exposed on the system and this can be queried.
The official definition of this extension is available here:
http://www.opengl.org/registry/specs/IMG/framebuffer_downsample.txt
