    cogl-path: Generate the primitive before using it for clipping
    
    The data->fill_primitive member is meant to be generated on demand in
    an accessor function. However when using it for clipping the code was
    trying to directly use it without calling the accessor so it would
    crash if nothing else caused the primitive to be generated. This was
    making the texture-fbo test in Clutter crash.
