Summary of changes

• Detect fling gesture on layer surfaces
  
• Update to wlroots 0.17.3
  
• Apply drm panel orientation. This can be disabled via
  phoc.ini. This might require adjustments to the mount matrix to make sensor
  orientation match screen orientation.
  
• Fix assertions and crashes related to output removal
  
• Allow to tweak layer surface stacking
  
• Issues fixed:

Detailed changes

phoc (0.40.0) experimental; urgency=medium
.
  * keyboard: Modernize indent.
    PhocKeyboard is one of the earlier GObjects. Let it catch up with
    current indent.
  * keyboard: Use C style comments
  * keyboard: Chain up to parent's constructed first.
    We want to initialize the parent first. The other children of
    PhocInputDevice to that correctly already.
  * keyboard: Move signals above class
  * subprojects: Update wlroots to 0.17.3
  * tracing: Drop unused variables
  * gesture: Fix indent
  * cursor: Name drag gesture accordingly.
    This makes it distinguishable from other gestures.
  * cursor: Drop cursor_gestures_handle_event.
    We can fold it into handle_gestures_for_event_at
  * layer-shell-effects: Reduce time for fold/unfold animation.
    Feels more snappy without being too hectic.
  * gesture: Allow to retrieve last event sequence
  * layer-shell-effects: Split out is_handle check.
    Will be useful in a follow up commit
  * layer-shell-effects: Allow to fling fold/unfold a draggable surface.
    When the velocity is high enough the surface fold/unfold is animated.
    We don't take the velocity into account for the animation.
  * cursor: Detect swipe gestures.
    Apply them to draggable layer surfaces if present. This allows to
    fling them away with a high velocity swipe gesture.
    Closes: https://gitlab.gnome.org/World/Phosh/phoc/-/issues/284
    Closes: https://gitlab.gnome.org/World/Phosh/phosh/-/issues/792
  * output: Handle NULL output gracefully.
    It's a bit simpler than adding `if (!output)` at the call sites
  * seat: Handle NULL output gracefully.
    We can't arrange layers on gone outputs.
    Closes: https://gitlab.gnome.org/World/Phosh/phoc/-/issues/257
  * desktop: Simplify phoc_desktop_surface_at.
    The function becomes quick to parse if we remove the assignments
    out of the if() clauses and get the output coordinates upfront
    as they apply to both layer surface blocks.
  * desktop: Add wlr to desktop_surface_at.
    Makes it consistent with phoc_view_get_wlr_surface_at
  * output: Get getter for wlr_output.
    We catch lots of errors via type asserts so add a getter with
    that.
  * output: Clear wlr_output->data pointer.
    This points to self which is about to be finalized, clear it out so
    other parts don't access the gone output.
  * desktop: Don't forget to remove the gone output from the layout.
    Closes: https://gitlab.gnome.org/World/Phosh/phoc/-/issues/155
  * tests: Use MALLOC_PERTURB_
  * layer-surface: Add layer getter
  * layer-shell-effects: Drop hash table for alpha layer surfaces.
    We don't need to look up by layer surface so no need to maintain the
    hash.
  * output: Make phoc_output_for_each_surface private
  * output: Clarify phoc_output_get_layer_surfaces_for_layer
  * output: Use a GQueue for the layer surfaces.
    This allows us to go forward and backwards easily.
  * desktop: Use phoc_output_get_layer_surfaces_for_layer.
    This makes sure we confine the layer surface iteration to
    PhocOutput.
  * output: Unify layer surface iteration logic.
    Use phoc_output_get_layer_surfaces_for_layer to iterate the
    surfaces in phoc_output_layer_for_each_surface. This unifies
    layer surface iteration in one place.
  * output: Move queue ownership to output.
    This will allow us to cache it
  * output: Cache layer surface ordering.
    Instead of recalculating on each access cache the ordering
    and make bits that might change the ordering (such as committing
    a layer surface) invalidate the cache.
    This also works towards removing more double accounting in this area.
  * layer-shell-effects: Allow to tweak stacking.
    The stacked-layer-surface protocol allows to stack a layer surface
    directly above or below another layer surface.
  * desktop: Allow to get layer surface stacks
  * output: Process layer surface stackings
  * ci: Fix drm backend build on alpine.
    It needs libdisplay-panel-info
  * doc: Document help and disable-animations flag
  * settings: Split out boolean option parsing
  * output: Simplify update_output_manager_config
    wlr_output_configuration_head_v1_create already sets the values from
    the passed in output.
  * output: Apply drm panel orientation.
    If `drm-panel-orientation` is set to `true` in phoc.ini apply the panel
    orientation transform by default.
    Closes: https://gitlab.gnome.org/World/Phosh/phoc/-/issues/192
  * utils: Ignore displays that encode aspect ratio rather than size.
    This is based on sway's 2f84d6e349d12f3293c44268bc5c8551340e5787 which
    in turn got inspired by mutter.
  * output: Allow to configure physical width and height.
    This can be useful in case edid is off or if we're on a nested
    display (like Wayland or X11)
  * output: Print output info at the very end.
    This allows us to see (possibly overridden) physical size.
