[mkgmap-dev] Trouble getting some multipolygons to render inmkgmap

Not sure if it maters. But in JOSM validator it reversed water:land not on
left side.

This is why I thought it was correct.

Markus,

Thanks for looking into this.  Are you sure the sense of the way around 
water matters?  I know that it is important for coastlines, but couldn't 
find any suggestion that it matters for other inland water masses, e.g. 
natural=water (http://wiki.openstreetmap.org/wiki/Tag:natural%3Dwater) 
doesn't mention it.

Also, the multipolygon "usage" section on the wiki 
(http://wiki.openstreetmap.org/wiki/Relation:multipolygon) states:
"The direction of the ways does not matter"
