All 2D coordinate spaces in Cogl have their origin at the top-left so we shouldn't be flipping the coordinates we pass to cogl_framebuffer_swap_region to be relative to the bottom of the framebuffer. This bumps the Cogl version requirement to 1.7.5 since we've had to fix a bug in the semantics of cogl_framebuffer_swap_region. Reviewed-by: Neil Roberts <neil@linux.intel.com>
