Comment 6 for bug 1104511

Depends.

If you're using unity, the switcher is in unity itself and uses the
same code as the launcher to render the icons. See
unity/launcher/BamfLauncherIcon.cpp

If you're using compiz without unity, it would be staticswitcher,
which is really just using the same code from compiztoolbox
(compiz/plugins/compiztoolbox/src/compiztoolbox.cpp)
