'''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:
http://www.opengl.org/registry/specs/MESA/framebuffer_flip_y.txt
