This function disables drawing outside the selected rectangular field. The clipping x and y coordinates are defined
by the values, in pixel units, programmed in four clipping vertex registers TDGC_CXMINR, TDGC_CXMAXR,
TDGC_CYMINR, TDGC_CYMAXR. Clipping is enabled by setting CEN bitfield in TDGC_CCR.
