+.SH NAME
+gl_setwritemode \- set the font writemode flags
+
+.SH SYNOPSIS
+.B #include <vgagl.h>
+
+.BI "void gl_setwritemode(int " m );
+
+.SH DESCRIPTION
+Sets the writemode flags for the font routines. It must be the sum of exactly
+one choice out of the following two groups:
+
+.PD 0
+.TP
+.B WRITEMODE_MASKED
+.TP
+.BR WRITEMODE_OVERWRITE " (default)"
+.PD
+If
+.B WRITEMODE_MASKED
+is set, only foreground pixels of the font
+are used for write operations; the screen background is not
+erased.
+
+
+.PD 0
+.TP
+.B FONT_COMPRESSED
+.TP
+.BR FONT_EXPANDED " (default)"
+.PD
+If
+.B FONT_COMPRESSED
+is set, text writes will use the compressed
+bit-per-pixel font rather than the expanded font (which would be slightly faster).
