[mkgmap-dev] [PATCH v1] - misc fixes to subdivision area splitting

From Mark Burton markb at ordern.com on Sat Sep 5 00:32:49 BST 2009

In trying to determine the cause of the problem that Felix has reported
when tiles use a lot of polygon styles, I have been looking at the code
that divides areas into "subdivisions". The attached patch (applies to
1170) makes a few changes in that department. It is not expected to fix
the polygon problem but it should be otherwise beneficial in that it
will reduce the number of subdivisions created.

Please do test this patch, especially if you are processing complex
maps as I don't want to commit it until it's had a good bashing.

I have processed all of GB and NL without problems.
