[Gtk-sharp-list] [PATCH] Fix custom CellRenderer creation

[Andy York]

I have been working on this with no success as well, I was attempting to 
use Gdk.Drawable as my base instead of inheriting from a CellRenderer. 
Because the CellRenderer seems to be just a drawing of text, image, etc. 
I didn't feel there is much benefit to inheriting from a CellRenderer. 
But I am not very good with Gtk yet so that could be completely wrong.

I'm looking forward to learning the answer to this as well, but I have a 
feeling is simply involves writing text on a Drawable area.
