[mkgmap-dev] New code for splitting polygon

Sun Jan 8 10:30:13 GMT 2017

Hi Ticker,

I think you can take the tests in uk.me.parabola.util  in mkgmap/test as an example.
And sorry, I should already have coded one for clipSinglePathWithSutherlandHodgman().

Hi Gerd

Will do. Can you point me to an example of the preferred style for a
