NAME
gl_compileboxmask - compress a masked bitmap
SYNOPSIS
#include <vgagl.h>
void gl_compileboxmask(int w, int h, void *sdp, void *ddp);
DESCRIPTION
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.
