Adds support for cosmic-workspace-v2 pin, unpin, move_after, and
move_before requests.
Both features need some work with workspaces span displays mode, so that
will need more fixes later.
We also want to generate a unique id for pinned workspaces to send in
the ext-workspace-v1 protocol. But that isn't a strict requirement for
anything. So I haven't yet fully implemented that. We'll also want to
persist other things, like workspace naming when that's added.
Overall, though, with separate workspaces per display, this is working
pretty well.
If two displays have the same edid (which shouldn't happen, since edid
includes a serial number, but is somewhat common in practice with
identical monitors), match output stack by comparing both edid and
connector name.
If we get the same edid but a different connector, `set_output`
truncates but also adds the new one. (Before adding edid matching, this
would have just added to the output stack.)
`prefers_output()` will requrire a connector name match if the edid of
the current output is the same as that of the output being compared.
If the user explicitly moves a workspace to an output, assume that is
where the user wants it, so it shouldn't be moved back to a different
output in the future.
For persistent workspaces, the explicitly set workspace is the one that
will be stored, instead of trying to track an unbounded list of outputs
persistently.
Requires https://github.com/Smithay/smithay/pull/1676.
This changes two things:
* `Workspace::is_empty` no longer checks if there are activation tokens,
but a separate `Workspace::can_auto_remove` checks if the workspace is
empty and has no activation tokens.
- When we add workspace pinning, that can also be checked there.
* `Workspace` no longer contains a `pending_tokens` list that is updated
on `refresh`. Instead, `can_auto_remove` takes the xdg activation
state as an argument.
Since `Workspace::refresh` normally is run for focused workspaces, this
fixes allowing non-focused workspaces to be removed when an activation
token expires. It seems generally good to avoid tracking the activation
tokens in two places, and this is probably more efficient than needing
to refresh in more places.
By splitting this, we still don't remove an empty workspace if it has a
pending activation token, but we also don't add an empty workspace for
an activation token.
This mitigates the confusing behavior with activation tokens that aren't
used, but having to wait a few seconds in some cases before a workspace
is removed is still a little confusing. (We probably want `cosmic-term`
and `cosmic-workspace` to either consume the activation tokens they are
passed, or not be passed tokens when started by keybinding?)

This new protocol extends `ext-workspace-v1` with the same additional
functionality `cosmic-workspace-v1` provided. Toplevel info and toplevel
management are also updated to use ext handles, and there's an image
source for ext workspaces.
For now, the old protocol is still supported.
It would make sense to have a bound like
`for<'frame> R::Frame<'frame>: AsGlowFrame<'frame>`. But that appears to
not behave properly due to current limitations of the borrow checker:
https://blog.rust-lang.org/2022/10/28/gats-stabilization.html#implied-static-requirement-from-higher-ranked-trait-bounds
Instead, this makes `glow_frame` and `glow_frame_mut` associated
functions of the `AsGlowRenderer` trait. Then it is pretty
straightforward to make the `RenderElement` implementations generic
using that and `FromGlesError`.
It would make sense to make `Self::Error: FromGlessError` a requirement
of the `AsGlowRenderer` trait, but due to the lack of implied bounds
support, that produces a bunch of errors about missing bounds. If Rustc
improves that eventually, some bounds could be cleaned up a bit:
https://github.com/rust-lang/rust/issues/44491
`(w_elements, p_elements)` tuples are used in a bunch of places. A
struct with named fields is generally an improvement just due to the
fact the order is non-obvious.
But we can also add methods. In particular,
`extend_from_workspace_elements` abstracts out some of the more
redundant code in `workspace_elements`.
It would be nice to avoid allocation everywhere, but iterators would
complicate lifetimes, run into issues with needing multiple mutable
borrows to things like the `Renderer`, and be awkward in certain
functions without generator syntax. In any case, cosmic-comp already
relies on allocating vectors here.
If this abstraction is commonly useful in compositors, perhaps it could
be moved to Smithay.
Don't just check maximized windows on every refresh, remapping them and
causing flickering, but introduce a proper recalculate method to be
called on layer-shell events / set_output event.
Also if we need to remap, remap all windows to keep stacking order.
Using `is_tiled()` here doesn't work for fullscreen windows, since
`is_tiled()` returns `false` for them.
This (plus the previous changes for supporting minimize) seems to fix
the behavior of `SDL_MINIMIZE_ON_FOCUS_LOSS` in XWayland applications
(https://github.com/pop-os/cosmic-comp/issues/231). Wine had a similar
issue, though I haven't tested it yet.
It doesn't seem ideal visually that the fullscreen window becomes tiled
then minimized itself, but that's less of a problem.
May need to check if this is an issue with any other uses of `is_tiled()`
or `is_floating()`.
