'''OpenGL extension MESA.framebuffer_flip_y

This module customises the behaviour of the 
OpenGL.raw.GLES2.MESA.framebuffer_flip_y to provide a more 
Python-friendly API

Overview (from the spec)
	
	This extension defines a new framebuffer parameter,
	GL_FRAMEBUFFER_FLIP_Y_MESA, that changes the behavior of the reads and
	writes to the framebuffer attachment points. When GL_FRAMEBUFFER_FLIP_Y_MESA
	is GL_TRUE, render commands and pixel transfer operations access the
	backing store of each attachment point with an y-inverted coordinate
	system. This y-inversion is relative to the coordinate system set when
	GL_FRAMEBUFFER_FLIP_Y_MESA is GL_FALSE.
	
	Access through TexSubImage2D and similar calls will notice the effect of
	the flip when they are not attached to framebuffer objects because
	GL_FRAMEBUFFER_FLIP_Y_MESA is associated with the framebuffer object and
	not the attachment points.

The official definition of this extension is available here:
