like adding a gratuitious feature, GL target users can crosshair 3 for a completely new crosshair and higher resolution crosshair (oooh!) Software renderer doesn't have it because...well look at Draw_Crosshair() in draw.c, it's truly a nightmare! You have to plot each pixel individually, makes you feel like you're coding in Applesoft BASIC. If you want it, figure out how to do it sanely.
