This protocol allows clients to attach a toplevel window to an ongoing
drag-and-drop operation, enabling features like browser tab tear-off.
The attached toplevel follows the cursor during the drag, moving as if
xdg_toplevel.move was called. The window is automatically detached when
unmapped or when its surface is destroyed.
Implementation details:
- Listen to both unmap and destroy events on the toplevel surface to
properly clean up when the surface is destroyed while still mapped
- Emit new_toplevel_drag event when a drag is created, allowing
compositors to track attached toplevels
- The toplevel pointer becomes NULL when detached, which compositors
must handle during motion events.
This is needed for cases where the touch operation goes over a region
where no surfaces are present. In this case, we'd want to notify the
touch grabs (for example DnD grabs) that no focus is currently focused.

When an FD is passed to xcb_connect_to_fd(), xcb takes ownership of that
FD and is responsible for closing it, which it does when
xcb_disconnect() is called. But the xwayland handler code also keeps a
copy of the FD and closes it via safe_close() in
server_finish_process().
This double-close can cause all sorts of problems if another part of
wlroots allocates another FD between the two closes - the latter close
will close the wrong FD and things go horribly wrong (in my case leading
to use-after-free and segfaults).
Fix this by setting wm_fd[0]=-1 after calling xwm_create(), and ensuring
that xwm_create() closes the FD if startup errors occur.
The important bit here is whether this is using a single or two
sub-passes. The flag isn't used for anything else.
Preparation for an upcoming one-subpass codepath.
Upon leasing, the wlr_drm_lease_connector_v1 will be automatically clean up by the wlr_output
destroy handler. There is no need for the wlr_drm_lease_manager to keep track of leased connectors.
We were iterating over involved outputs, applying the new state and
sending the commit event for each one. This resulted in commit
events being fired while we weren't done applying the new state for
all outputs.
Fix this by first applying all of the states, then firing all of
the events.
Closes: https://github.com/swaywm/sway/issues/8829
Add wlr-internal enums for the properties specified in
color-representation-v1 (encoding, range, chroma siting, alpha mode) so
that other parts of wlroots can use these without depending on the
protocol specifics and without needing to include the protocol headers.
Also add conversion functions to convert the protocol enum values into
the wlroots enum values.
