We're now sharing most of the X11Client activity behavior accross all
clients. This allows to cleanup some of the existing virtuals and remove
quite a bit of code overalls.
Has to introduce an extra platform specific hook since X11Client
serializes the activity information in an atom and we will probably need
to do something similar on the Wayland platform at some point.
This allows us to start interacting with the activities with kwin
wayland. They are not restored properly accross sessions though since
nothing is really persisted and the session management still seems to
be amiss.
Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.
This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.
We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.
