[mkgmap-dev] type=multipolygon relations

Sat Jan 18 15:43:33 GMT 2014

Hi WanMil,

no, I don't think so. I seem to remeber in some cases it caused 
trouble in the mp code itself, but forgot the exact case, I just found this relation
while trying (again) to change mp code (and Java2DConverter) to use high precision.
