                 Key: GEOT-2086
                 URL: http://jira.codehaus.org/browse/GEOT-2086
             Project: GeoTools
          Issue Type: Sub-task
          Components: core render
            Reporter: Simone Giannecchini


QueryLayer method should be more resilient when trying to filter out the 
feature by bbox. Now we try to reproject the requested envelope back to the 
feature CRS but this may cause problems when the requested envelope is 
partially overlap the area of definition of the features' crs (exceptions are 
spit out very nicely). We should try to be a bit proactive here and in case of 
an error involve the area of definiton of the feature crs and reverse the check 
so that can still proceed. The extrema ratio could be loading them all, but 
still that's better than throwing an exception and showing nothing.
