/*
 * A memory pixrect is a special type of pixrect.  Its image resides in
 * memory, in a publicly known format permitting more direct access to the
 * image than possible with the general pixrectops.
 *
 * In the memory pixrect the image is stored in consecutive memory locations,
 * across the row from left to right, and then from top to bottom.  Each row
 * is padded to a 16-bit or 32-bit boundary (for details refer to the Pixrect
 * Reference Manual).
 *
 * The depth of a pixel is the number of bits required to represent it.
 * Pixels are placed in consecutive fields of width the depth of each pixel,
 * with placement being independent of word or byte boundaries.
