I've looked at the gtktreeview.c source and this is what I found:

- starting with GTK 2.7.0, the background area got 2*focus-line-width 
widget style added to the vertical size (focus-line-width defaults to 1)
- starting with GTK 2.7.3, it got changed from 2*focus-line-width to 
vertical-separator (set to 2 and read-only as far as I understand it 
from GTK)

I didn't find a clean way to figure out the size until I think the 
treeview has been exposed. At least it doesn't seem to work consistently 
in the method that matches the row heights because I get a null path 
that is needed in the call to get the background area height. So, a hack 
to this would be to add vertical-separator to the row height if GTK >= 
2.7.0. This wouldn't be perfect if widget styles can be changed somehow. 
Any comments? Any know if widget styles can be changed from their default?
