       gl_expandfont - expand a packed pixel font


       #include <vgagl.h>

       void gl_expandfont(int fw, int fh, int c, void *sfp, void *dfp);


       Convert  a  bit-per-pixel  font at sfp with 256 characters of size (fw, fh) to an expanded
       font of character pixmaps, stored at dfp (size will be 256 * fw * fw    *  BYTESPERPIXEL).
       All non-zero pixels are set to color c.

       It  is  possible  to  use  non  expanded fonts (but it is slower) when the FONT_COMPRESSED
       gl_setwritemode(3) flag is set.
