These two new main states are determined by looking at the programs the
user has open. The artist state, using the new artist catdog, is
triggered by PixelPaint and FontEditor, and the inspector state is
triggered by Inspector, Profiler and SystemMonitor. This requires CatDog
to unveil /proc/all, and, for some reason, /etc/passwd.
CatDog's state was previously handled by a bunch of booleans that all
needed to be in sync pretty accurately, but some of these are exclusive
(like alerted and sleeping). This commit introduces a simple enum for
the main states of CatDog which exclude the roaming and direction
states. The main state determines the standing image of CatDog and will
have further effects in the future.
The only remaining sync call from client to server is now the call
that switches a window's backing store. That one actually relies on
the synchronization to hand over ownership of the backing stores,
so it has to stay synchronous for now.
