Do you know that adding values to a unique value renderer gets significantly slower the more values are added?

I have code back at the office for demonstrating this.

Troy-

Just to clarify, am I correct that this is a workaround for the issue you are hitting with the symbols coming out of DictionaryRenderer being either too big or too small? If so, the ideal fix is that we can get you a way to modify symbol size in the DictionaryRenderer directly so you can get rid of the workaround.
