Seamshot Calculator

Ray collision detection with brushes in Source-based games have a bug allowing you to shoot through some of the seams. We call them seamshots (more info on that here.) This little tool of mine was created to find these seams in any given Portal 2 BSP map, and give you a list of sar_drawline commands in a config file which you can execute in game to see all of the seams. False positives are undoubtedly certain, and colors make absolutely no sense, but it's enough for me so heck it, releasing the tool so maybe someone else can fix it for me lol.
