       gl_compileboxmask - compress a masked bitmap

       #include <vgagl.h>

       void  gl_compileboxmask(int  w,  int  h,  void  *sdp, void

       Convert the rectangular masked bitmap of size  (w,  h)  at
       sdp  to  a  compressed  format that allows faster drawing,
       which is stored at ddp.  Allocating w * h  bytes  for  the
       compiled  version is usually enough; an upper limit should
       be (w + 2) * h.

       Compiled bitmaps are only supported in  linear  256  color

       It is very likely that both are at least  to  some  extent

       Occasionally  this  might  be  wrong. I hereby asked to be
