Based on the proposal of Ralf Kleineisel the patch tries to cut multipolygons at multiples of 2048 in Garmin coordinates. This reduces artefacts at the cut lines of the multipolygons.
The patch contains also a fix for the bug found by Nakor (Some inner areas are ignored in mulitpolygon processing).
Please test it soon. I plan to commit that within the next 2 days if noone complains about it.
I tested this patch, and it does not seem to break anything for me. I have not paid attention to the number of multipolygon cut lines in the past, so I cannot say if this patch reduces them considerably.

If someone can compile a jar file for me I'd like to test this. I recently built a map of Thailand and Malaysia and with all the islands the multipolygon artefacts in Mapsource are quite extreme.
