Thats why I prefer a handle per widget. I don't like widgetset which
paint all them selves.
The choice you make depends on if you draw all yourself or you use
native widgets. I can only speak from experience with the latter.
Thats why I mention it.

Even with customdrawn subcontrols, I see a benefit in clipping you will
get when you use a handle per widget.

Don't know if you can partially paint windows on X11, but I would avoid
updating a whole form each time some control has changed.
