[1.1.42] Selecting a wall ghost draws a solid interior

[PFQNiet]

Steps to reproduce:
- Place four wall ghosts in a square
- Move (empty) mouse cursor over the ghost walls

Observed behaviour: three out of the four walls, when hovered, will make the interior "filling" of the wall be drawn solid, not ghosty.

Thanks for the report. It was not drawing as solid, just the filler was drawn multiple times. Fixed for 1.1.43.
