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 sync includes minor non-breaking updates from recent years:
- Fix typos and grammatical issues (e.g. "a an" → "an", "inexistent" → "nonexistent")
- Improve description consistency with `wl_output` (e.g. name, description, make, model, serial)
- Add `destructor` annotation to relevant events (e.g. `finished` in foreign-toplevel)
- Clarify event emission timing and behavior for output management
- No functional or semantic protocol changes introduced
These changes improve the accuracy and consistency of protocol descriptions without impacting compatibility.
We grab header files from there, ensure include directories are
properly set up when building wlroots.
Fixes missing header files when a wayland-protocols subproject is
used.
We've actually been doing the wrong thing this whole time, for v1 of the
protocol, we should set the refresh_nsec field to 0 if the output does
not have a constant refresh rate. However we've been setting it to the
fastest rate instead since eac7c2ad2f
which is incidentally exactly what v2 of the protocol proposes.
So allow advertising v2, and fix v1 to set refresh_nsec to 0.
This implements the new ext-foreign-toplevel-list-v1 protocol [1].
Implemented analog to the zwlr-foreign-toplevel-management-v1 implementation.
The additional _ext_ in the names was added to avoid name collisions.

Implement a basic version of linux-dmabuf-unstable-v1 version 4.
Only default hints are implemented.
The new wlr_linux_dmabuf_feedback_v1 data structure will allow
compositors to define their own custom hints in the future. This
data structure makes it easy to describe feedback metadata.
It's converted to a "compiled" form suitable for marshalling over
the Wayland socket via feedback_compile.
