 *
 * @details		The GDISP module provides high level abstraction to interface pixel oriented graphic displays.
 *
 * @pre			GFX_USE_GDISP must be set to GFXON in gfxconf.h
 *
 * @note		Each drawing routine supports a gdispXXXX and a gdispGXXXX function. The difference is that the
 * 				gdispXXXX function does not require a display to be specified. Note there is a slight anomaly
 * 				in the naming with gdispGBlitArea() vs gdispBlitAreaEx() and gdispBlitArea(), the latter of
 * 				which is now deprecated.
