Small optimization for usages of Minecraft.getGLMaximumTextureSize(), only need to calculate it once.
Small bugfix in Stitcher that was preventing ti from fully filling the possible texture space. Should lower the amount of empty space in textures.
Optimize Texture loops a bit for non-rotated textures. Should help the FPS loss on higher resolution texture packs. If it becomes a major issue we may have to look into a more  optimized animation system.
