Move horizontal/vertical warp backgrounds to separate buffers

Browse source 
Instead of using the same tower buffer that gets used for towers, use a
separate buffer instead so there's no risk of stepping on the tower
buffer's toes at the wrong point in time.

This commit combined with the previous one fixes #369.
