Falling Donut block uses tile in weird location

[zaidalkaz]

You can change the Donut Block graphic in \blocks\donutblock.png, but when a Donut Block falls it uses the texture found in \tilesets\Classic\large.png. Below is a picture showing where the Donut Block is found in the Classic tileset (It's near the right edge):

It would make the game more mod-friendly if the graphic used in donutblock.png would also be used for a falling Donut Block, instead of this specific graphic in the classic tileset.
