Eric Fischer	380550ce85	Remember to remove the closepath after clipping away a polygon	2014-12-04 14:54:11 -08:00
Eric Fischer	b7b476b36c	Don't introduce bogus geometries in clipped-away features.	2014-12-03 16:30:35 -08:00
Eric Fischer	08ff40e42f	Trying to follow Vlad's suggestion and work from the top down. ... Doesn't quite work yet, but seems like the right thing to do. From the bottom up, indexing is a mess because of the buffering, and includes unneeded areas in the bounding boxes of big features.	2014-12-03 16:18:43 -08:00

Eric Fischer	3cd6fcfbe0	Add option to set buffer size. Pass it through to clipping functions.	2014-10-27 13:20:17 -07:00
