Subject: INTEGRATION: CWS presfixes03 (1.16.42); FILE MERGED 2005/04/14
 12:08:54 thb 1.16.42.1: #i46805# The GraphicCache errorneously used a cached
 bitmap, prepared for a monochrome VDev with draw mode BLACKBITMAP, for normal
 output. Fixed by a) ruling out BLACK/WHITE_BITMAP for caching at all, and b)
 storing both bit depth and draw mode of target outdev in the
 DisplayCacheEntry
