It doesn't seem like there's really a need to have `Err(_)` and `Ok(None)`.
`Err(_)` means the set exists for the output, but doesn't have the
appropriate workspace index. It's a bit odd that the set not even
existing becomes `Ok(None)`.
Instead, just return `Err(InvalidWorkspaceIndex)` in either case.
I hoped to split this up into multiple commits, but the api
changes to `shell/workspace.rs` were to invasive to feasibly do this.
Here is a rough list of changes:
- Fullscreen windows aren't mapped to other layers anymore
- This they need their own logic for:
- Sending frames
- Dmabuf Feedback
- Primary outputs
- On commit handlers
- cursor tests
- They get their own unmap/remap logic
- They get a new restore state similar to minimized windows
- Refactored the minimized window state to reuse as much as possible
here
- They need to be part of focus stacks, which means adjusting them
to a new type `FocusTarget` as they previously only handled
`CosmicMapped`.
- Various shell handlers (minimize, move, menu) now have dedicated
logic for fullscreen surfaces
- This was partially necessary due to relying on CosmicSurface now,
partially because they should've had their own logic from the
start. E.g. the context menu is now reflecting the fullscreen
state
- Fullscreen windows may be rendered behind other windows now, when they
loose focus.
- This needed changes to input handling / rendering
If the window is part of a stack, remove it then map it outside of the
stack, before calling `Shell::move_window.` Somewhat similar to the code
in `Shell::move_request`.
It would be more elegant if `move_window` handled this in some way, but
I can't think of a way to change the API there that would be better than
this.
(Perhaps some of the naming of methods could also be updated, given
"window" in functions like this means a `CosmicMapped`.)
Protocol support for moving workspaces would also be useful, but should
involve a new protocol object representing the stack.
Fixes https://github.com/pop-os/cosmic-workspaces-epoch/issues/41.
Iterating over `.windows()` for each workspace does not iterate over
`minimized_windows`, so `from_workspace` was not found. Simply changing
this to use `element_for_surface` and `space_for` (like `fullscreen` and
`unfullscreen`) fixes this.

Though it does unminimize the window, which we may also want to change.
Previously, alt-tab wouldn't actually focus a window if it was on
another output, since the active output/workspace was unchanged.
We need to move the cursor if we activate a window on another output.
