Toplevel repaint issue.

There are some cases where we only need to clear a certain region of the screen. We don’t need clear all screen if it only a minor part needed to repaint. So I think that the Redraw methods had a region as parameter because it could be any frame dimensions we want to pass to it. So in the image you see that the TextField at the bottom and the StatusBar disapear and there are not redrawed again while dragging. Without these features it’s not worth it developing dragging at all. I think that my original suggestion to resolve this is better.

I now see what @bdisp has been trying to articulate in this case. My apologies for being persistent on this, but after pouring over the entire project I’m hyper sensitive to people using the APIs correctly.

Now that I’ve authored a comment in the code in Window.MouseEvent, I understand and see that @bdisp was correct:

	// SetNeedsDisplay takes super-view relative coordinates, so use Frame
	Application.Top.SetNeedsDisplay (regionToRedraw);

	// Redraw the entire app window using just our Frame. Since we are 
	// Application.Top, and our Frame always == our Bounds (Location is always (0,0))
	// our Frame is actually view-relative (which is what Redraw takes).
	Application.Top.Redraw (Frame);

@tig I really appreciate your great work with no doubt and I congratulate you for your great job, but for now I don’t see other way to work around it, for now. We can wait until discovery another solution. In the meanwhile if you want I can close the PR.
