Style properties are not covered by the API freeze; if we implement
such a "theme decides whether entire area needs to be redrawn" then it
would be a style property.

Or we might just say that gradient themes can't make toplevel windows
covered by gradients...

And no, redraw_on_allocate() is not at all useless even if we always
invalidated the background of the window. It's still useful for window
widgets: which was what it was intended for originally.

Things like GtkTextView, GtkTreeView, GtkViewport can win big by not
redrawing the entire area when allocated bigger.
