* 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.
