Detailed changes

phoc (0.51.0) experimental; urgency=medium
.
  [ Gotam Gorabh ]
  * tree: Prefer char over gchar
.
  [ Sebastian Krzyszkowiak ]
  * seat: Use the getter to access focused layer's output.
    This gracefully deals with the case where seat->focused_layer->output is NULL.
.
  [ Guido Günther ]
  * server: Dispose renderer first.
    We create the backend before the renderer and should dispose them
    in opposite order. This fixes a crash when cleaning up the pixman
    renderer on alpine.
.
phoc (0.51~rc1) experimental; urgency=medium
.
  * render: Use pixman_region_empty()
    We can expect recent enough pixman that supports this nowadays.
  * render: Exit early when there is no damage.
    As touch-points and debug-damage submit proper damage nowadays there's
    no point in proceeding. Software cursors are only rendered when they
    overlap with the pass in damage either.
    This has the nice side effect that we don't emit any tracemarks when
    there was nothing to render.
    We keep emitting `render-end` for the moment until we received that signal
    from the output shields.
  * output: Move pending finish closer to commit.
    No need to keep it around longer
  * output: Use pixman_region_empty()
    We can expect recent enough pixman that supports this nowadays.
  * output: Drop pointless call to wlr_output_transformed_resolution()
    Fixes: 550062499 ("wlroots: Upate to 79e06303")
  * output: Drop pointless copy
    wlr_output_state_set_damage() copies aready so no need to copy
    it upfront.
  * output: Damage output early.
    This ensures we have a sufficiently sized damage size early on.
  * output: Damage whole output.
    Instead of just adding the current damage_ring (of whatever size)
    ensure the damage ring's buffer covers the whole output.
  * output: Drop check for debug_damage.
    When we render debug-damage the damage-ring will contain the
    damage information for the rects to render so damage_ring.current
    will already be non-empty.
  * output: Damage output when transform/scale/mode changes
    wlr_damage_ring_set_bounds() damaged the whole buffer. Since that
    is gone we need to do that on our own.
    Fixes: 550062499 ("wlroots: Upate to 79e06303")
  * ci: Update shared scripts to 5cd8a21
  * ci: Switch to Debian forky
  * wlroots: Switch to 0.19.2
  * server: Dispatch idle loop in prepare.
    Without this we might have the idle callback not running when there are
    no events. This can result in e.g. the workspace indicator not going away
    until e.g. the mouse moves.
  * ci: Switch to newer forky
  * seat: Destroy seat views before cursor.
    Destroy a seat view invokes `phoc_cursor_set_mode` so we
    need to do that first.
    We can't use `g_clear_pointer` as that seats the given pointer
    to `NULL` before invoking the free func. This breaks fails as
    `seat_view_destroy` still accesses `priv->views`.
    As `phoc_seat_handle_destroy` does the same we need to guard
    against double cleanup. We'll disentangle that further when
    looking at multiple seats.
  * server: Kill spawned child gracefully.
    So far we just went away. Instead pass the `SIGTERM` on to
    the child so it can clean up.
    On 2nd `SIGTERM` we exit gracefully.
