gtkrc-2.0 properties setting for GtkCellRenderer

[Lynn Kerby <lfk kerbit net>]

I don't like the default padding in GtkCellRenderer and would
like to be able to set the ypad property globally in my gtkrc.
This doesn't seem to work:

style "mydefaults"
{
  GtkTreeView::expander_size = 10
  GtkTreeView::vertical_separator = 0
  GtkCellRenderer::ypad = 1
}

class "GtkWidget" style "mydefaults"

The expander_size property for the TreeView does work, is
there simply no support for rc settings on CellRenderer
properties?
