Cogl aims to consistently put the origin of 2D objects at the top-left instead of the bottom left as OpenGL does, but there was an oversight and the experimental cogl_framebuffer_swap_region API was accepting coordinates relative to the bottom left. Cogl will now flip the user's given rectangles to be relative to the bottom of the framebufffer before sending them to APIs like glXCopySubBuffer and glBlitFramebuffer.
