Eh okay, it's been a while, but
this version should at least not exit with an error on old graphics cards, but instead will just look really ugly.
That's because apparently Intel cards and really old (<2001) graphics cards don't support textures with a size other than powers of two so the texture has to be rescaled. There's solutions to that so it won't look that bad, but it's all a bit hackish but I'll do it at some point (unless someone else wants to..).
Posted it in the wrong thread at first...
