(svn r10980) -Fix [FS#1158] : This will hopefully fix the case of an assert that happens when an industry uses a special gfx index (tile spec 0xFF). This 0xFF is the sentinel of a special check done for oil rigs, where water need to be around, but no tile will be constructed on it.

Problem is that the upper limit of gfx tiles is currently at 175.  So, of course the system will assert with 255 ;)
