Improve spatial filter performance with Prepared Geometries
-----------------------------------------------------------

                 Key: GEOT-2226
                 URL: http://jira.codehaus.org/browse/GEOT-2226
             Project: GeoTools
          Issue Type: Improvement
          Components: core filter
    Affects Versions: 2.5.2
            Reporter: Jesse Eichar
            Assignee: Jesse Eichar
            Priority: Minor


I need to reuse a filter many thousands of times.  It is a standard use case.  
One side of the filter is a literal geometry and the other is obtained from the 
feature.  The literal geometry is very large and could be a prepared geometry 
to improve the performance characteristics of the spatial filters.  

Since this is a common use case we could check the expressions and for the 
literal expressions in the filter a prepared geometry could be cached and used 
for the calculation.
