[mkgmap-dev] Optimizing MapSplitter

Hi Gerd,

I have compiled the same map with your patch, file is here:
http://files.mkgmap.org.uk/download/225/29483020.7z

Map is a bit smaller and really has less subdivisions, see comparison:
fist compilation 29483019.img
level 4: resolution 17, subdivisions    1
level 3: resolution 18, subdivisions    4
level 2: resolution 20, subdivisions   35
level 1: resolution 22, subdivisions  221
level 0: resolution 24, subdivisions  367

patched 29483020.img
level 4: resolution 17, subdivisions    1
level 3: resolution 18, subdivisions    4
level 2: resolution 20, subdivisions   33
level 1: resolution 22, subdivisions  202
level 0: resolution 24, subdivisions  340

I can measure a small increase in zoom speed in my nuvi, like 5-10%, but 
this could be measurement error.
