Description
When you're messing with geometries it's handy to find out the reason why they're invalid. GEOS >= v3.1 supports GEOSisValidReason()
for that purpose - returning a string about why a geometry is invalid. The attached patch adds support to the GeoDjango GEOS bindings as GEOSGeometry.valid_reason
.
Tests, docs, and error-chucking for GEOS <v3.1 are included.

Updated the patch to make sure 3.1 is available before making prototype for GEOSisValidReason
(else there'd be an AttributeError
when trying to get function from C library). 99% ready for check-in, only thing that's bugging me is whether we should rename property invalid_reason
, because users are only checking when geometries are invalid.

Yeah, I was in two minds as well. You do get a "Valid Geometry"
message. TBH i would have preferred None
or ""
but I didn't want to forcibly change the return value. +0
