Detailed changes

phoc (0.50.0) experimental; urgency=medium
.
  [ Evangelos Ribeiro Tzaras ]
  * workspace-manager: Fix format specifiers for workspace index
.
  [ Guido Günther ]
  * output: Add element type annotation
  * output: Allow to add blings.
    Implement the interface similar to other objects that
    can have blings.
  * render: Render output blings.
    The need to be rendered after all views to be visible.
  * bling: Only render when bling is mapped
  * workspace-indicator: New bling to show worspace number
  * desktop: Show workspace indicator on workspace changes
.
phoc (0.50~rc1) experimental; urgency=medium

  [ Guido Günther ]
  * doc: Document `adaptive-sync`
  * doc: Add a slug.
    Otherwise it appears in the docs as "Unknown document"
  * workspace: Introduce workspaces.
    A workspace groups a set of views in layout coordinates. We only
    display one workspace (called `active`) at a time. Views can move
    between workspaces while layer-surfaces are always rendered on all
    workspaces.
    The workspace manager keeps track of the existing workspaces.
  * desktop: Instantiate workspace manager.
    We add the workspace manager, listen to workspace changes and provide
    getters, so other parts of the stack can access those too.
  * keybindings: Allow to switch workspaces
  * keybindings: Allow to move windows between workspaces
  * render: Only render active workspace.
    The other views remain "hidden" until their workspace becomes the active
    one.
  * output: Only use direct scanout if view is on active workspace
  * view: Iterate over workspaces.
    If this becomes to cumbersome we could keep a hash map (wlr_surface,
    view) of all views on the desktop.
  * desktop: Let phoc_desktop_for_each_view iterate all workspaces
  * desktop: Manage the workspace queue rather than global view queue.
    Operations are per workspace now.
  * desktop: Damage output areas that change between workspaces
  * desktop: Drop get_views() and the view queue.
    Everything is per workspace now
  * doc: Document new gsettings.
    Helps: https://gitlab.gnome.org/World/Phosh/phoc/-/issues/330
  * desktop: Remove unused headers
  * cursor: Don't include touch-point in header.
    Let's be more specific as it speeds up compilation
  * cursor: Move view moving code to separate function
  * cursor: Move view resize code to separate function
  * cursor: Save one indent level by exiting early
  * desktop: Support cursor-shape-v1 protocol.
    Avoids some duplicate cursors when e.g. resizing GTK4 apps
  * server: Fix indent
  * server: Use g_idle_add_once.
    It's less error prone
  * server: Bump nofile soft rlimit to the hard limit value.
    Lets not run out of file descriptors when a client requests
    a lot of buffers.
    We restore the rlimit before forking of the child process.
    Closes: https://gitlab.gnome.org/World/Phosh/phoc/-/issues/415
  * pointer: Use libinput's LIBINPUT_CONFIG_DRAG_LOCK_ENABLED_STICKY.
    Recommended in the libinput 1.27 release notes:
    https://lists.freedesktop.org/archives/wayland-devel/2024-November/043860.html
  * layout-transaction: Remove unused headers
  * layer-shell-effects: Drop unused headers
  * layer-shell: Include correct headers.
    We can minimize the included headers a bit
  * seat: Rename allow_input to is_input_allowed.
    We check rather than changing the mode
  * cursor: Fix function name.
    The prefix is `phoc_cursor_`
  * layer-shell: Drop unused seats argument from update_cursors()
    The function gets the seats on its own.
  * layer-shell: Update cursor when arranging surfaces.
    The code so far only updated the cursor for the layer surface
    but we need to take the case into account where a layer surface
    moves away and reveals a non layer-surface.
    Otherwise we might get the wrong cursor when we e.g. close
    phosh's overview and the cursor is over an app.
  * seat: Revert "Reject input based on shell state too"
    This breaks (among other things) type to search in Phosh after startup.
    We want to fix that at the input level rather than avoiding
    that the surface gets focus.
    This reverts commit 4f22f58a95af938f129cf9b532d7284a79524dfa.
    Reopens: https://gitlab.gnome.org/World/Phosh/phoc/-/issues/228
  * wlroots: Update 0.19.1
.
  [ Sebastian Krzyszkowiak ]
  * render: Invert the surface transform before applying.
    The Wayland protocol specification says this about wl_surface::set_buffer_transform:
       This request sets the transformation that the client has already applied to
       the content of the buffer. (...) The compositor applies the inverse of this
       transformation whenever it uses the buffer contents.
    phoc currently did the opposite (applying the specified transform to the received
    buffer), which is a regression since 0.37.0 (for output rendering) and 0.45.0
    (for thumbnails).
    Make it work as specified again by applying the inverse of the buffer transform.
    Fixes 0e31b45f6 ("render: Switch to wlr_render_pass")
    Fixes a51f7cd13 ("render: Switch thumbnail rendering to new render API")
