 * The XYINDEX macro computes the index to the starting byte (char) boundary
 * for a bitmap_unit containing a pixel with coordinates x and y for image
 * data in XY format.

	285	* normalization and calls a routine to do so if needed. The logic in
	286	* this module is designed for LSBFirst byte and bit order, so
	287	* normalization is done as required to present the data in this order.
	288	*
	289	* The ZNORMALIZE macro performs byte and nibble order normalization if
	290	* required for Z format data.
	291	*
	292	* The XYINDEX macro computes the index to the starting byte (char) boundary
	293	* for a bitmap_unit containing a pixel with coordinates x and y for image
	294	* data in XY format.
	295	*
	296	* The ZINDEX* macros compute the index to the starting byte (char) boundary
	297	* for a pixel with coordinates x and y for image data in ZPixmap format.
