This<br />
change forwards the KWin::Application's signal that the xcbConnection<br />
changed to the EffectsHandler so that the effects can respond to it.</p>
<p>All effects which announce a support property connect to this new signal<br />
and re-announce the property. In case the xcb connection died (future<br />
XWayland crashing case) it is set to XCB_ATOM_NONE by that. In case the<br />
xcb connection got created (future delayed XWayland startup) the atom is<br />
set to the proper value.</p>
<p>In addition all usages of the support properties are guarded, so that no<br />
nonesense actions are performed if the support property is XCB_ATOM_NONE.</p></div></div><br /><div><strong>TEST PLAN</strong><div><p>Only compile tested as we don't have XFree KWin yet</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R108 KWin</div></div></div><br /><div><strong>BRANCH</strong><div><div>effects-xcb-connection-changed</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D7761" rel="noreferrer">https://phabricator.kde.org/D7761</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>effects.cpp<br />
