//bugs.freedesktop.org/show_bug.cgi?id=2879) attachment #2287
    (https://bugs.freedesktop.org/attachment.cgi?id=2287) Follow-up to
    bugzilla #1299: Add new visuals in the Postscript DDX (including
    TrueColor 16bit, PseudoColor 15bit/12bpg(12 bits per R-, G-, B-channel
    as in PostScript Level 2 (and above) colors can have 12 bits per
    component (36 bit for RGB)), PseudoColor+GrayScale+StaticGray
12bit/12bpg) and switch the default visual from PseudoColor 8bit/8bpg to
    PseudoColor 12bit/12bpg.

* 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.
