NAME
       gl_setwritemode - set the font writemode flags

SYNOPSIS
       #include <vgagl.h>

       void gl_setwritemode(int m);

DESCRIPTION
       Sets the writemode flags for the font routines. It must be the sum of exactly one choice out of the following two groups:

       WRITEMODE_MASKED
       WRITEMODE_OVERWRITE (default)
	      If WRITEMODE_MASKED is set, only foreground pixels of the font are used for write operations; the screen background is not erased.

       FONT_COMPRESSED
       FONT_EXPANDED (default)
	      If  FONT_COMPRESSED  is  set,  text  writes will use the compressed bit-per-pixel font rather than the expanded font (which would be
	      slightly faster).
