[mkgmap-dev] omit items from overview

Hi Ticker,

Yes this does work, but you are right that the test for isOverviewComponent or isOverviewCombined only needs to test for isOverviewComponent and it doesn't need the change to OverviewMapDataSource.

Please find an updated patch attached.

Hi Mike

Does this work? There is no information about the tagging when the
elements are read back from the ovm_ file.

In MapBuilder I think you have to test for isOverviewComponent rather
than isOverviewCombined and I don't think changes to
OverviewMapDataSource make any difference to anything.
