kwin/atoms.cpp
Martin Gräßlin 108252194a Use Xcb::Atom in KWin::Atoms to resolve all atoms
During startup we only create the request, the reply will be fetched
once the atom is needed.

To make proper use of this async behavior the creation of Atoms is
moved directly to the claim of the manager selection, so they can be
fetched while we wait for the previous manager selection to give up
on it.
