    stage: Push framebuffer before setting up viewport
    
    When capture_view* functions are called with the paint flag set
    to TRUE, we need to setup the framebuffer, however this was
    happening after setting up the viewport, while the viewport
    needs the framebuffer to be valid when calling cogl_set_viewport.
