 * for a bitmap_unit containing a pixel with coordinates x and y for image

	278	*
	279	* The XYNORMALIZE macro determines whether XY format data requires
	280	* normalization and calls a routine to do so if needed. The logic in
	281	* this module is designed for LSBFirst byte and bit order, so
	282	* normalization is done as required to present the data in this order.
	283	*
	284	* The ZNORMALIZE macro performs byte and nibble order normalization if
	285	* required for Z format data.
	286	*
	287	* The XYINDEX macro computes the index to the starting byte (char) boundary
	288	* for a bitmap_unit containing a pixel with coordinates x and y for image
	289	* data in XY format.
	290	*
	291	* The ZINDEX* macros compute the index to the starting byte (char) boundary
	292	* for a pixel with coordinates x and y for image data in ZPixmap format.
