vga_drawscansegment — draw a horizontal line of pixels
int vga_drawscansegment(unsigned char *colors, int x, int y, int length);
draws a horizontal line of length pixels starting at position (x, y). The colors drawn are taken from color .. color[length - 1]. Svgalib versions prior to 1.2.10 required x, y, and length to be multiples of 8. This is no longer true. In high/truecolor modes, the length must be given in bytes, not pixels.

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.
