TGA or PNG crosshairs require support for corresponding image formats
to begin with, and that's something I still didn't do (I'm lazy I
guess..) There's the "crosshair 2" mode for quite some time, but I
guess that won't be as satisfactory.

I don't think this would happen in 1.5.6. Noted for newer releases.
