 * Macros
 * 
 * The XYNORMALIZE macro determines whether XY format data requires 
 * normalization and calls a routine to do so if needed. The logic in
 * this module is designed for LSBFirst byte and bit order, so 
 * normalization is done as required to present the data in this order.
 *
 * The ZNORMALIZE macro performs byte and nibble order normalization if 
 * required for Z format data.
 * 
 * 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.
 * 
 * The ZINDEX* macros compute the index to the starting byte (char) boundary 
 * for a pixel with coordinates x and y for image data in ZPixmap format.
