32d33e2b to pyxie fixes to add padding to vertical sprites; i'm going to need to change these, and make more special fields, that horizontally, vertically, with padding, and with different image justifications (justify left vs right)
1f2b5694 to pyxie add ability to use an image list file to pyxie binary, fix a packing problem when we get into a situation where we've packed from the bottom going upwards; we fail to mark the corners correctly, and need an overlap check in the collision function; might be a good idea to mark the corners in this case, provided we can figure out which rectangle we're trying to place on
