Request: ResizeableWindow::setBorderThickness

I want my content to fill the entire window (desktop application). I am using a DocumentWindow, which in turn inherits from ResizeableWindow. The problem ist: The ResizeableWindow has a default border, which I cannot seem to change.

Therefore it would be very nice to have an additional function called ResizeableWindow::setBorderThickness, which lets me set the border size to zero.

If you set the border to zero, then it won't be resizable. So there'd be no point in using a ResizableWindow at all, and you might as well just put it in a plain old TopLevelWindow.

(But isn't is possible to change the border thickness with LookAndFeel?)
