wmii/TODO.wmii-4

Ordered list of TODOs:

- apply the focuscolor patch by Stefan Tibus
- introduce a view stack to focus the previously selected view on view destruction
- remove swapping action, merge vertical swapping into moving - is this a good idea?
- idea for column mode:
	100: is the current default mode with fallback (shows arbitrary clients)
	0: is the current max mode, shows only one client at the time (same bahvior
			as current) n: shows n clients, in stacking mode, using the
	selected client as center,
		n == 1 is current stacking mode,
		n == equal will use the center of (n/2),
		n == unequal has always a center element.
	Visible clients should only change when a formerly hidden
	(stacked) client is made visible.  So, when the fifth client is focused
	and made visible, the third would disappear (with n=2) -- this means on
	boundaries, like in mutt(1).
- /def/ncol defines num of columns which should be created by default if possible.
- wmiimenu -t <title> flag
- remove the geom syntax as it is now (with the +- stuff, and only
	allowing explicit coordinates, instead additionally resize
	+/-<w> +/-<h> and move +/-<x> +/-<y> actions are needed in the
	associated ctl devices of clients.  
- add wmiir ls (read should have same semantic as in 9p), output without
	details, add -l for details like in ls of Plan 9
- remove internal labels, now tagging seems easy and straightforward that they
	THINK: We'll need CreateTag, DestroyTag, UnfocusTag, FocusTag and the
	event loop in wmiirc must be before TAGGING can be externalized again
- liblitz: window abstraction (creation, events), can be reused in menu and bar
	and frames
- tagbars
- screen dimension rescaling if screen resolution changes (even with Xrandr)
- Xinerama support
- partial EWMH support
- libixp: idea from PoP: implement a va_args method similiar to printf for
	marshalling 9P messages, might reduce LOC drastically
