- * Macros
- *
- * The ROUNDUP macro rounds up a quantity to the specified boundary,
- * then truncates to bytes.
- *
- * 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 macro computes the index to the starting byte (char) boundary
- * for a pixel with coordinates x and y for image data in ZPixmap format.
