Sorry, I should have explained a bit more.  That thing got added between
GTK+ 2.6 and 2.8:

2005-04-28  Owen Taylor  <otaylor redhat com>

	* gtk/gtkwidget.c: Add a draw-border style property to allow
	themes to draw outside the widget's allocation.

I'm not completely sure where this is needed, but apparently some
specific themes need it.  It may be the Win32 or the MacOS X theme.

This obviously hurts quite a bit when repainting a single button many
times.  I wonder if it even shows up in the profile when exposing a
"real" window with many different widgets.

I'd be interested in knowing how much time the children of that call
take up in the profile.  Is the problem finding out the correct style
structure?  Or is it asking the style if it has that property?  Etc.
