The example can be seen at the style guide.

IrisGridRenderer and GridRenderer now use different cell renderers depending on the type.

Not part of your change, but just something that bugs me - textOverride is a property that's really only relevant to the TextCellRenderer, not the general CellRenderer case. I feel like the text override (which is only really used in IrisGridRenderer to display null or empty in a specific case) should be pushed down into model.textForCell, and even have a model.fontForCell... there may have been other implications for why we didn't do that. @mattrunyon added it as part of PR #408 , but it doesn't look like I had any comments there about pushing textOverride down to the model and why we went with the direction we did.

Looking great! As discussed, will not be merging until start of May.
