[geos-devel] transformation of geometry

[Mike Toews]

See this enhancement:
http://trac.osgeo.org/geos/ticket/687

which would ideally be modelled after the JTS Class AffineTransformation
the http://www.vividsolutions.com/jts/javadoc/com/vividsolutions/jts/geom/util/AffineTransformation.html

With PostGIS, ST_Affine is implemented with liblwgeom, which considers
affine transformations in 3D space:
http://trac.osgeo.org/postgis/browser/trunk/liblwgeom/lwgeom.c#L1646
http://trac.osgeo.org/postgis/browser/trunk/liblwgeom/ptarray.c#L1674
