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 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).

It is very likely that both are at least to some extent are due to Harm Hanemaayer <H.Hanemaayer@inter.nl.net>. Occasionally this might be wrong.
