Re: [Geotools-devel] LiteRenderer2 rendering bottle necks and performance issues

[<gr...@ax...>]

I'm finding myself a bit lost here, so need to confirm if the following 
was already discused:

is there, or shouldn't be, a way of issuing a feature request which 
contains the geometry/coordinatesequence factory one want the datastore 
to use? I mean, this way a renderer could pass a geometry factory that 
performs decimation and even whose geometries implement Shape. By the 
other hand, if your'e going to do topology operations you can pass a 
default one or whatever. It would be just a matter of enforcing all 
datastores to rely on the geometry factory supplied by its client.
was it already discused?
