Bring app to the top of the z-order when user clicks on any of it's windows.

[memecode]

If I have an application with a modal dialog (that has B_MODAL_SUBSET_WINDOW_FEEL set and the parent window has been added to the dialog via AddToSubset) open above it's main window. And there is another application obscuring the dialog, the user can't bring the desired application to the front without moving or hiding the foreground application.

Ideally clicking the main window (which is inactive but partially visible) would bring the whole window stack to the top of the z-order so the user can finish interacting with the (previously hidden) active dialog. Currently the click does nothing because the parent window is made inactive by the modal dialog. The application remains below the foreground app.
