These routines provide a high-level interface to the QuickDraw and 
Color Manager routines which allow the creation and manipulation 
of off-screen bitmaps and pixel maps.  They are designed to run on 
any machine with 128K or later ROMs (sorry 64K ROM fans).

Note that the design incorporates the idea that you can go along 
pretending there is an off-screen buffer, even when one could not 
be allocated, and the calls will do nothing.
