It so happens that in my current project the toolbar potentially
changes all the time. And in this specific case sending a redraw
covering the whole window is the right thing to do.

You mean the AES would not send a redraw message when the toolbar
height increases? But what about the workarea? Either the AES blits it
itself, which means that the window height changes, or it doesn't, in
which case it must send a redraw message.
