xfwm4 changes

[Thomas Leonard]

Hi guys,

I thought I'd try switching to xfwm4 for a bit. I'm planning to make a few
changes for a ROX version, possibly using a configure argument
(--with-rox-ui?) or a fork, if that's inconvenient for you.

My first patch (attached) is not ROX-specific; it stops xfwm4 from
deadlocking in a server grab on startup (the first Gtk application to use
pango causes a font cache window to be created, but xfwm4 aleady holds an
X server grab when it tries to do this).

After that, my plan is:

- Change the behaviour of button-3 on the window frame. Click-release will
  pop up the menu as now, but click-drag will work like using button-1 but
  without raising the window. Allows windows to be moved and resized
  without raising them.

- Get rid of the raising behaviour in some other places (eg, raise on
  click in the main area). Should this be an option?

- Allow options to be changed at run-time. Is this currently possible?
  Eg, changing the theme without restarting. I haven't looked into it yet,
  but it should be possible to have a configure option to either compile
  a ROX-Filer style in-process options box or an XSettings-client system
  for changing the prefs.

Quite impressed with it already, though :-)
