window decoration for multiwindow mode

[Harold L Hunt II]

Ralf,

I believe Kensuke's new window manager for multi-window mode does this 
(the one that works with miext/rootless).  The code is not yet 
completely checked in, but check the archives for messages he has posted 
pointing to some test versions.  You can check out the code for the 
server from our xorg repository on freedesktop.org, but the xwinwm code 
is on Kensuke's personal site until I get it checked into the xclients 
repository.

I believe he may find this reference information useful, though.

I know that he based it off of another window manager, so he should be 
handling most of the ICCCM specs for window decoration, etc.
