       gl_compileboxmask - compress a masked bitmap


       #include <vgagl.h>

       void gl_compileboxmask(int w, int h, void *sdp, void *ddp);


       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 modes.

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

       Occasionally  this might be wrong. I hereby asked to be excused by the original author and
