From the start I have found the concept of a window manager weird. It's like a
crippled gui tool kit plugin. Cripled because it can only handle window
borders.
One way to avoid having to do full redraw of revieled - (is that spelled
correctly btw? I was amazed not being able to find it in my dictionary. :)
- areas would be to always have all windows fully rendered and buffered. When
you move a window you would then blit the window to the new position and the
revieled areas would be blitted from the buffer.
Check out photon gui for qnx.

If you cover an IDL visualisation window, the contents are not redrawn. You
just get a black window. Though you could say that this is just IDLs fault, I
would argue that it really should be the guis job to handle window refreshes.
Other than that you raise some valid points.
