[regression] Maximized window gets unredirected when it's not fullscreen

Bug Description

[Test Case]

1. Maximize a Thunderbird window.
2. Use it, right click on it, switch workspaces several times.
-> Make sure that eventually, the Thunderbird window (or some other invisible window) does not get unredirected. Clicking on the panel or launcher should work correctly.

[Regression Potential]

Unredirect fullscreen windows not working in certain cases.

Original description:

Using the latest lp:compiz and lp:unity...

1. Maximize a Thunderbird window.
2. Use it, right click on it, switch workspaces several times.
3. Eventually, the Thunderbird window (or some other invisible window) gets unredirected. After that, clicking on the Unity panel/launcher has no effect.

The mysterious window gets redirected and Unity comes back to life if you open a new window on top. e.g. Ctrl+Alt+T.

* debian/patches/revert_fix_994841.patch,
debian/patches/revert_fix_933776_955035.patch
- Removed, upstreamed
* debian/watch:
- Changed to the correct LP tarball path
* debian/patches/compiz-package-gles2.patch:
- Updated GLES patches to properly apply to the new compiz version

[ Timo Jyrinki ]
* New upstream release.
- Compiz won't start if "unredirect fullscreen windows" is enabled
(LP: #980663)
- "Unredirect Fullscreen Windows" stay on top (unredirected) even
when they're not on top any more (or the output is transformed)
(LP: #1041047)
- Unredirect Fullscreen Windows sometimes fails to unredirect fullscreen
windows at all (LP: #1041066)
- "Unredirect Fullscreen Windows" stay on top (unredirected) even when
an RGBA window is stacked above it (LP: #1046661)
- scale mode is not visible if a fullscreen window is unredirected
(LP: #1047168)
- Unredirecting a fullscreen window on a secondary monitor causes that
monitor to flicker (LP: #1050749)
- "Unredirect Fullscreen Windows" makes multi-monitor rendering much
slower (LP: #1051885)
- [regression] Maximized window gets unredirected when it's not
fullscreen (LP: #1053902)
- Unredirected fullscreen windows freeze and stay on top when wall
sliding (Ctrl+Alt+Left/Right) (LP: #1084401)
- "Unredirect Fullscreen Windows" can cause significant tearing on
fullscreen windows (especially playing video) on some drivers
(LP: #1051802)
- HTML5 video in Firefox continues to tear (LP: #1086337)
- Add support for blacklisting some drivers from using unredirected
fullscreen windows. By default intel and nouveau on Mesa 8.0
are blacklisted, configurable via ccsm. Users can upgrade to
Mesa 9.0 around 12.04.2 time. (LP: #1089246)
- Unredirect fullscreen windows should be the default for optimal
performance (LP: #1063690)
* debian/patches/workaround_broken_drivers.patch:
- Updated to apply.
* debian/patches/force_unredirect_enabling.patch:
- Enable unredirect_fullscreen_windows unconditionally. Because of
gconf hurdles we can't easily migrate existing users into the
new default otherwise. Unredirection can be easily disabled with
the new unredirect_match option, by blanking it completely,
including removing the '(any)' part.
* debian/patches/compiz-package-gles2.patch:
- Update for the new blacklisting feature as well
* debian/patches/blacklist_no_xml_double_escaping.patch:
- Cherry-pick fix for the default string (LP: #1091103)

[ Michael Terry ]
* debian/patches/blacklist_no_xml_double_escaping.patch:
- Update to also blacklist Mesa 9.0, which precise users may have from
the x-updates PPA. 9.0 seems to have similar problems as 8.0 on
Intel hardware.
