[mkgmap-dev] Include the following patches into trunk -- Patch3 - "reduce-point-density-polygon"

From Felix Hartmann extremecarver at gmail.com on Tue Mar 1 19:39:03 GMT 2011

Now I have been using this patch a long time and , and it really works 
fine. It applies the DP filter against polygons with a different 
agressiveness than for lines. This is really useful because strong DP 
filter against lines looks really bad, while for polygons the visual 
quality is degraded less.

I currently use /--reduce-point-density=4 and 
This is perfect for older GPS like etrex to have speed improvements but 
no drop in visual quality. Also in Mapsource / Qlandkarte GT this works 
very well. For Oregon or Dakota I would use something like 2.6 (default 
current behavior) and 5.2

Archived Discussion can be found here: 
Patch by Johan Gail, working very well since then. (well only that it's 
not yet set in the help file, so I have to use --x in front of the option)

I added a part2 -- to add the option to the help file, and allow it to 
be used without --x on the mkgmap call.
