* wip * getting stuff set up so we can actually run test cases * better handle block entry stuff * types2 working on gstring * comments * math ref working * up to first stack stuff * stack fixes * bounding box * math stuff is working * float fixes * temp debug for (method 9 profile-array) * stupid stupid bug * debugging * everything is broken * some amount of type stuff works * bitfield * texture bitfields not working * temp * types * more stuff * type check * temp * float related fixes for light and res problems * revisit broken files, fix bugs * more types * vector debug * bug fixes for decompiler crashes in harder functions * update goal_src
