       gl_setwritemode - set the font writemode flags

       #include <vgagl.h>

       void gl_setwritemode(int m);

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

       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_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).

       demo as well as of the original documentation is  unknown.

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

       Occasionally this might be wrong. I  hereby  asked  to  be
