Added monochrome and color DHGR initialization depending on the
horizontal resolution. 560x192x1 images are displayed in JACE without
color fringes. Should be tested with real hardware.
COMPTS is already initialized with READBMP. COMPTD has to be
initialized instead. Otherwise a small shift appears in the image. This
was not visible on the original demo picture because of the surrounding
black background.
Removed one unnecessary assignment to BUFFDST since it was already
written on screen and will be overwritten thereafter.
