\fB\fC\-ab\fR or \fB\fC\-\-detect\-shared\-borders\fR: DEPRECATED. In the manner of TopoJSON \[la]https://github.com/mbostock/topojson/wiki/Introduction\[ra], detect borders that are shared between multiple polygons and simplify them identically in each polygon. This takes more time and memory than considering each polygon individually. Use \fB\fCno\-simplification\-of\-shared\-nodes\fR instead, which is faster and more correct.
.IP \(bu 2
\fB\fC\-aL\fR or \fB\fC\-\-grid\-low\-zooms\fR: At all zoom levels below \fImaxzoom\fP, snap all lines and polygons to a stairstep grid instead of allowing diagonals. You will also want to specify a tile resolution, probably \fB\fC\-D8\fR\&. This option provides a way to display continuous parcel, gridded, or binned data at low zooms without overwhelming the tiles with tiny polygons, since features will either get stretched out to the grid unit or lost entirely, depending on how they happened to be aligned in the original data. You probably don't want to use this.
