   4 Subject: [PATCH] Don't break grab and focus state for a window when redirecting it.
   5
   6 Composite uses an unmap/map cycle to trigger backing pixmap allocation
   7 and cliprect recomputation when a window is redirected or unredirected.
   8 To avoid protocol visible side effects, map and unmap events are
   9 disabled temporarily.  However, when a window is unmapped it is also
  10 removed from grabs and loses focus, but these state changes are not
  11 disabled.
  12
  13 This change supresses the unmap side effects during the composite
  14 unmap/map cycle and fixes this bug:
  15
  16   http://bugzilla.gnome.org/show_bug.cgi?id=488264
  17
  18 where compiz would cause gnome-screensaver to lose its grab when
  19 compiz unredirects the fullscreen lock window.
