Introduce a per-window rule `<taskbarScope>` that controls where a window's
*taskbar entry* appears. This affects taskbar listing only (via foreign-toplevel
output membership); it does not change sticky/omnipresent state, focus, or
workspace membership.
Supported values (case-insensitive):
- here -> show only when both match: the window's monitor AND its active workspace
- monitor -> show only on the window's monitor, across that monitor's workspaces
(default if the key is omitted)
- workspace -> show on all monitors currently on the window's workspace
- everywhere -> show on all monitors and all workspaces
Currently, the dependencies between foreign-toplevel[-internal],
ext-foreign, and wlr-foreign are cyclical and a bit complex.
I suggest we reorganize it into a simpler hierarchy:
foreign-toplevel/
-> foreign.c/h
-> (depends on) ext-foreign.c/h
-> (depends on) wlr-foreign.c/h
The refactored code is smaller and (IMO) easier to follow.
In detail:
- Add include/foreign-toplevel folder mirroring src/foreign-toplevel
- Split foreign-toplevel-internal.h to ext-foreign.h and wlr-foreign.h
- Eliminate ext-/wlr-foreign.c -> foreign.c reverse dependencies
(including internal signals and foreign_request* functions)
- Make struct foreign_toplevel private to foreign.c
Lightly tested with qmpanel (which uses wlr-foreign-toplevel).
v2: reorder foreign-toplevel internal API funcs
This commit moves the check against server->input_mode from the callers
of desktop_focus_view() into desktop_focus_view() itself. This
eliminates code duplications and makes it harder to mess up the window
stacking order while window switching.
I also added the same check in view_minimize() so that minimize requests
from panels never messes up the window stacking order (I think only this
should be described in the release note).
