NAME

       gl_line - draw a line

SYNOPSIS

       #include <vgagl.h>

       void gl_line(int x1, int y1, int x2, int y2, int c);

DESCRIPTION

       Draw a line from point (x1, y1) to (x2, y2) inclusively in color c.

       You should not assume that the same drawing trajectory is used when you exchange start and end points.

       To  use  this  program  one first sets up a mode with a regular vga_setmode call and vga_setpage(0), with
       possibly a vga_setlinearaddressing call.  Then a call to gl_setcontextvga(mode) is made.  This makes  the
       information about the mode available to gl_line.

       The pixels are placed directly into video memory using inline coded commands.
