Improved splitter

25
May

Splitter now has a new split algorithm that usually results in fewer, more evenly sized tiles.

The test generator is > 10 times faster. This allows a deeper search for good splits. A few errors where fixed which sometimes prohibited to find a good split, but also sometimes helped to find one.

A new option --search-limit can be used to increase/decrease the amount of time the splitter tries to find a good split. The larger the input file the higher this value should be. For planet, --search-limit=1000000 is okay, --search-limit=10000000 is better.
