    stage-cogl: pass top-left relative swap_region coords
    
    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.
