+ (NPLANES =4), stored as 4 separate bitmaps. The current bitmap is
+ indexed by global variable `plane', which can be reset by \specials. To
+ make things simpler, the paintjet palette is redefined so that
+ when only one bitmap has a pixel set at the appropriate position
+ you get the right colour. At present, if more then one bitmap has
+ a given pixel set, you get a colour determined by the sequence
+ red, green, blue, black (in order of increasing precedence). This
+ should be changed by removing corresponding entries in the other
+ bitmaps when the current colour is painted.
+ There is one \special{color <red|blue|green|black>}.
+ Transparency mode is assumed -- this should be a command-line
+ switch.
