vga_drawline - draw a line on the screen
int vga_drawline(int x1, int y1, int
x2, int y2);
draws a line from (x1, y1)
on the screen. If you exchange
start and end of the line you should not expect the exactly identical set of
pixel be covered by the line.
This function is very inefficient as is does a bunch of vga_drawpixel
calls, you should consider using gl_line
(3) which is very efficient, or
doing direct screen access instead or use vga_drawscansegment
handle more than one pixel.
The color drawn is set with vga_setcolor
(3) or vga_setrgbcolor
The function always returns 0 (on which you should probably not really rely).
