It works well on Windows, only problem I found is it is ignored when 
hovering the author or date panels right to the graph panel.

On MacOSX it works only in the diff and file panels. Scroll speed is OK.

I would like to fix these before integrating the patch.
Anyway thank you very much for this, I was really missing it.
