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.
