compensate for the larger marker, or -rf*number* to allow at most *number* features in the densest tile.
* -g _gamma_ or --gamma=_gamma_: Rate at which especially dense dots are dropped (default 0, for no effect). A gamma of 2 reduces the number of dots less than a pixel apart to the square root of their original number.
### Line and polygon simplification
* -S _scale_ or --simplify=_scale_: Multiply the tolerance for line and polygon simplification by _scale_. The standard tolerance tries to keep
the line or polygon within one tile unit of its proper location. You can probably go up to about 10 without too much visible difference.
### Doing more
* -ac or --coalesce: Coalesce adjacent line and polygon features that have the same properties.
