Revision 965026

Chainsaw rendering fixes and performance improvements
 - previously if you expanded a row by shrinking its width (with wrap enabled), the row would never shrink in height - now it will
 - commented out use of an expensive cell height calculation method - no longer calculating the height, letting Swing calculate it for us
 - LoggerNameTreePanel implemented Rule, but triggered propertychange events caused by Swing, which were triggering rule re-evaluation...panel no longer implements Rule - no longer unnecessarily re-running rule evaluation
