gl_setfont man page
gl_setfont — set the text font to be used
void gl_setfont(int fw, int fh, void *fp);
Use the font stored as character bitmaps at fp, with characters of size (fw, fh), as the basic font for write operations. Note that the font included in the library must be expanded first, because it is stored bit-per-pixel; this is not required if the FONT_COMPRESSED gl_setwritemode(3) flag is set.

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. I hereby asked to be excused by the original author and will happily accept any additions or corrections to this first version of the svgalib manual.
