Version mkgmap-r3351 was committed by gerd on Tue, 18 Nov 2014

improve MapSplitter:
- put large objects into there own sub division
- put fewer objects into one sub division if possible so that 
more smaller divisions are created
- when splitting: don't add the bounds of the virtual
area to the bounds of the division. 

The typical effects are:
- smaller overlaps which should result in faster
redraw times on the device
- sub divisions are just as large as needed to 
hold the contained objects
- slightly larger img files
