Clipping
This function disables drawing outside the selected rectangular field. The clipping x and y coor-
dinates are defined by the values, in pixel units, programmed in four clipping vertex registers
2DGC_CXMINR, 2DGC_CXMAXR, 2DGC_CYMINR, 2DGC_CYMAXR. Clipping is enabled by
setting CEN bitfield in 2DGC_CCR. Polygons filled using the hardware fill are also clipped to the
selected rectangle if clipping is enabled.
