Improved Icons

[Jermungandr]

Actually THAT is very easy in comparison. All you have to do is have it crop away the frame and then remove the common specific colors associated with the backdrop. As long as the sprite itself does not share any of shades of red used in the background (which would be very rare) you'd be left with the sprite alone on top of a transparent backdrop.

However this would leave you with very tiny preview sprites in comparison to the larger size that the new icon expects.
