just like the other new draw functions sv_cheats needs to be set to 1 for the debug rendering to be visible

the color is an index into the palette as illustrated here: https://quakewiki.org/wiki/Quake_palette

The function signature is:

void draw_line( vector start, vector end, float colormap, float lifetime, float depthtest ) = #82;
