 /* HP PaintJet driver based on dvijet (the escape sequences are very */
 /* similar), magnification stuff from dvitos (also 180 dpi) */

 /* The changes to the included files have *only* been made for */
 /* unsegmented-memory un*x */

 /* We allow 4 colours (including black, but not including white) 
    (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.

Use machine-specific coding here for efficiency.  For TOPS-20, we encode
9 bytes from every pair  of 36-bit words.

For each raster line on the paper, the Laser Jet expects a binary  8-bit
byte stream of the form

    <ESC>*bnnnWxxxxxxx ... xxxxxxx

where each byte contains, in order from high to low bit, a left-to-right
bit pattern.  No  end-of-line marker  is required;  the escape  sequence
automatically causes a new raster line to be started.
