Considering the quality of osm data it's good to be enabled by default,
but bad for debuging.
.mp files have it as parameter added in the last version.
from the cgps change log:
New parameter to define simplification level of Douglas-Peucker
simplification alg.
	[IMG ID]
	..
	SimplifyLevel=1
     	This allow to change simplification level of lines and polygons.
Allowed values between 0.1 and 10

Would it make sense to do a simplification per level let's say 24 bits
- 10m, 23 bits 20 meters, and so on ?
