The subsurface logic holds a self-reference to the WlSurface to
track stacking orders of the children relative to the parent. This
self-reference needs be dropped during cleanup to avoid reference
cycles.
This was not the case, and caused every surface user data to be
leaked as it kept a reference to itself (and all of its children).
This changes the state handling logic of wl_surface to automatically
track subsurface pending in the form of transactions. The role enum
(and the associated type parameter) is no more, and replaced by a
general-purpose typemap-like container on surfaces.
The new logic is introduced in the files:
- `src/wayland/compositor/cache.rs`
- `src/wayland/compositor/transaction.rs`
The rest of the PR is the fallout of these changes, as well as a few
trivial clippy fixes.
Rework the subsurface tree by:
- forbidding subsurface loops
- storing the relative depth of a parent to its children,
finally respecting the wl_subsurface specification.
closes#23
* Rename priviledged to privileged in backend/drm/mod.rs
* Fix a number of typos in comments
* Fix typos in string literals
* Wrap identifiers with backticks in doc comments
* Spelling and capitalisation in doc comments
* Use XWayland in comments
This seems to be the standard capitalisation, even though the executable
is called `Xwayland`.
* Use Glium instead of glium in comments
* Use DRM and API in comments
* Fix remaining occurrence of 'priviledged'
* Reformat code to appease Travis' rustfmt
