OpenGL extension MESA.pack_invert
This module customises the behaviour of the
OpenGL.raw.GL.MESA.pack_invert to provide a more
Overview (from the spec)
This extension adds a new pixel storage parameter to indicate that
images are to be packed in top-to-bottom order instead of OpenGL's
conventional bottom-to-top order. Only pixel packing can be
inverted (i.e. for glReadPixels, glGetTexImage, glGetConvolutionFilter,
Almost all known image file formats store images in top-to-bottom
order. As it is, OpenGL reads images from the frame buffer in
bottom-to-top order. Thus, images usually have to be inverted before
writing them to a file with image I/O libraries. This extension
allows images to be read such that inverting isn't needed.
