[mkgmap-dev] Commit: r1402: If a polish map contains any background polygons, don't generate one.

Version 1402 was commited by markb on 2009-11-22 22:21:55 +0000 (Sun, 22 Nov 2009) If a polish map contains any background polygons, don't generate one. Normally, a polygon of type 0x4b is automatically generated to cover the map's background. For OSM maps that can't explicitly contain such a polygon, this is reasonable. Polish maps can contain polygons of type 0x4b. So if a Polish map does contain any polygons of type 0x4b, suppress the automatic generation of the background polygon.
