(svn r21262) -Fix (r18708)[FS#4246]: Custom station foundations using the 'simple foundations'-method did not draw any sprite for WSE-slopes when there are foundations on both neighboured tiles in the north. As there must be at least one sprite to provide the correct offset for the groundsprite draw the (empty) default foundation sprite in that case.
