Lost fix from r1.112; add comment.
Mechanical change: group->gc
Add consistent checks against NULL.
Move client cycle grab/ungrab into a more relevant place; while here, update comments about why we need to grab/ungrab the keyboard.
Re-add lost chunk in group_cycle from r1.113.
Further simplify _NET_WM_DESKTOP handling using new group_assign().
oops; remove left over debug print
Allowing sending a valid 'nogroup' (0) group_ctx to group_assign() (since we init all groups), though assigning the client's group to NULL for 'sticky'; use this simplification in a few places (others to follow).
Split out sticky mode checks and the restoring of a client's group and _NET_WM_DESKTOP from the config-based auto-grouping; no (intentional) behavior changes. Needed for further work in cleaning up this area.
Implement _NET_CLIENT_LIST_STACKING (from Thomas Admin), but bottom-to-top order, as per spec (notified Thomas as well).
Don't allow freeze operations on fullscreen (consistent with what fullscreen does).
Sort _NET_WM_STATE Atoms like the spec.
Move CLIENT_STICKY logic from client hide/unhide to group hide/unhide; rationale being that clients should be able to hide/unhide independently of group switching.
Add Xkb modifier to ignore mask; from Alexander Polakov.
Fix whitespace.
Add client freeze extension to _NET_WM_STATE Atom, allowing flag to persist. As usual with new Atoms, requires X restart.
_NET_WM_STATE_STICKY implies only sticky at the group/desktop level, not position and size; based on discussion with a few.
Instead of special casing the 'term' and 'lock' commands, go back to keeping them hidden; showing them has apparently caused confusion/angst.
Leave command list order from .cwmrc alone; remove sort.
Bring group and client cycle closer together.
...
client_find valid resources as needed, relieving the need for
screen_find to ungracefully handle invalid root windows. Removes a long
standing XXX. Should theoretically allow XClientMessage handling on
more than one X screen. Alter callers of screen_find to handle
failures.
