There's no constraints on desktop and monitor names, therefore, using a
desktop or monitor name as descriptor is ambiguous.
We put an end to this ambiguity by introducing desktop and monitor IDs.
`bspc query -{M,D}` now yields IDs instead of names.
Fixes#397.
It is now easy to access any attribute by piping the output of
`query -T` to a JSON extractor/filter.
E.g.:
bspc query -T -d DESKTOP_SEL | jq -r .layout
And it also makes `restore -T` more robust.
Because many clients (e.g. termite) prevent us (maybe unknowingly) from
capturing motion events on their windows, we're forced to create a
window for this sole purpose.
Grabbing the pointer isn't an option, because it forces us to consider
some of the enter notify events we should be ignoring.
It appears that unmapping windows might generate undesirable enter
notify events. It can lead a very nasty bug where the focus constantly
switches between two desktops ad infinitum (cf. #268).
The last desktop and monitor are now deduced from the history.
The stacking order is now independent from the history of the focused
nodes: this prevents hacks on both sides.
All windows are now considered in the stacking algorithm: it prevents
tiled windows from one monitor to appear above the floating windows of
another monitor.
Transfered windows are stacked below the windows of the same kind.
Example: if one chromium window is opened and a link is opened in
newsbeuter then chromium will steal the input focus (without explicitly
requesting focus via the proper EWMH message).
The new message syntax:
- Provides 10 commands instead of 60.
- Allows multiple actions to be applied in one call.
The client now returns an non zero exit code when a message fails.
The `is_adjacent` function now handles vacant nodes.
