/**
 * Do a DMD transition.
 *
 * Transitions are complicated because the old/new images may have
 * different color depths (mono or 4-color).  Also, we can only map
 * two pages at a time, but there may be up to 4 different pages
 * involved.
 *
 * First, we check to see if both old and new images are mono.  If so,
 * then the transition can be optimized slightly.
 *
 * For debugging transitions, define STEP_TRANSITION.  The transition
 * will take place one frame at a time; use the launch button to
 * step through each frame.
