[mkgmap-dev] r3784 produces large img files than r3773

Tue Feb 7 12:17:41 GMT 2017

Hi Ticker,

that's what I expected. Most shapes do not have too many  points after line simplification.
If I got that right most of the code in PolygonSplitterFilter is now obsolete. I think it would be
better to move the functionality of PolygonSplitIfNeededFilter into it so that the history is kept.

Hi Gerd

I've done this and committed. In the examples I found, using
backtracking to split the polygon gave very slight size improvements
(best was about 0.05%)
