textureentry: add performance note list, text: fix mousewheel direction input: was going to add a deque to allow registering handlers in back and front. obviated by minimap fix, though. cleaned up a bit and renamed stuff (again, sigh). loaderthunks: fixed weird alignment/padding warning This was SVN commit r2979.
