Shapefile renderer needlessly clones style elements
---------------------------------------------------

                 Key: GEOT-2035
                 URL: http://jira.codehaus.org/browse/GEOT-2035
             Project: GeoTools
          Issue Type: Improvement
            Reporter: Andrea Aime
            Assignee: Andrea Aime
             Fix For: 2.5.0, 2.6-M0


Shapefile renderer clones rules in order to avoid modyfing them when geometyr 
filters are reprojected to the screen space (since the geometries are read from 
the storage already reproejcted in screen space). 
Yet, a geometry filter in an SLD is quite uncommon, before duplicating the 
filter (and thus loosing the caches stored in the literal expressions) it's 
better to check if there is an actual need for it. A simple visitor can assess 
if cloning the rules is really necessary.
