ResizableTall has problems being a sublayout

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Create a layout hook which will use ResizableTall as a sublayout, so it
will manage only a subset of windows, for instance put it into a DragPane
and put some windows in the second pane as well.
2. Send [Mirror]Shrink/Expand events

What is the expected output? What do you see instead?

Some random windows get resized, sometimes several windows at the same time
(e.g. if there are two ReisizableTall's in both parts of the DragPane),
sometimes none.

I expect only focused window to be resized.

What version of the product are you using? On what operating system?

Darcs version on Gentoo

This is due simply to the fact that ResizableTall assumes that it is managing 
all the
windows.  Unfortunately, many of the layouts (and perhaps the whole layout
infrastructure) are not designed with compositionality in mind.  Fixing this 
would be
a major (although perhaps worthwhile) undertaking.
