[0.8.8] arrow sprites are clipped at tile boundaries

[sparr]

I've modified core/graphics/arrows/*indication*.png and find that in-game they are clipped to game tile boundaries, even though the bounding box of the sprite is placed so as to overlap multiple tiles.

Hello, when you do this, you need to delete the crop-cache.dat file.
