Robert Bragg 6f79eb8a5a Use MESA_pack_invert to avoid read_pixels flip ... cogl_read_pixels returns image data in a top-down memory order, but because OpenGL normally returns pixel data in a bottom-up order we have to flip the data before returning it to the user. If the OpenGL driver supports the GL_MESA_pack_invert extension though we can ask the driver to return the data in a top-down order in the first place.
