[mkgmap-dev] New splitter version, big memory savings

L> And are (large) polygons that span many tiles fully supported?

The splitter has been able to handle relations that span an unlimited number 
of tiles since r49, and ways that span many tiles since r60 or so. As far 
as I'm aware the only remaining problem is that a node is still limited to 
4 tiles max. This limit can be exceeded with very small --max-nodes values, 
since the tiles can end up so small that their overlaps start to interfere 
with each other. A warning is displayed in this situation. I know how to 
fix this if need be (basically the same way I fixed it for ways and relations), 
though it introduces a minor performance and memory cost and I didn't think 
this was a problem in the wild.
