wlr_scene_output_layout_add_output() was made public by f5917f0247
("scene_output_layout: make output adding explicit") but the ownership
semantics are not obvious and should be clarified.
Up until now, frame/present events were only triggered when the
user submitted a buffer. Change the wlr_output API so that these
events are triggered when any commit is applied on an enabled
output.
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3708
When integrating wlroots with another toolkit, wlroots may receive
wl_pointer.enter events for surfaces not backed by a wlr_output.
Ignore such surfaces by tagging the ones we're aware of with
wl_proxy_set_tag().
Fixes an error seen in labwc CI builds with -Werror:
../subprojects/wlroots/include/wlr/types/wlr_gamma_control_v1.h:44:16:
error: ‘struct wlr_output_state’ declared inside parameter list
will not be visible outside of this definition or declaration [-Werror]
44 | struct wlr_output_state *output_state);
| ^~~~~~~~~~~~~~~~
The backend is not able to tell whether a surface is being
presented via direct scan-out or not. The backend will set
ZERO_COPY if the buffer submitted via the output commit was
presented in a zero-copy fashion, but will no know whether the
buffer comes from the compositor or the client.
Using "present" is confusing here: the event is emitted when the
buffer is being sampled to be displayed on an output, not when it's
being presented on-screen.
Rename to match the presentation-time terminology.
This function takes a pointer to memory with a hardcoded format
and many parameters to describe the pixel buffer.
wlr_output_cursor_set_buffer() can be used instead.
A saner replacement for wlr_cursor_set_image():
- Takes a wlr_buffer instead of numerous parameters and a hardcoded
format.
- The scale is not used to filter outputs.
- A ref to the buffer is kept to apply it to new outputs.
This changes the semantics of wlr_output_state. Instead of having
fields with uninitialized memory when missing from the committed
bitflag, all fields are always initialized (and maybe NULL/empty),
just like we do in wlr_surface_state. This reduces the chances of
footguns when reading a field, and removes the need to check for
the committed bitfield everywhere.
A new wlr_output_state_init() function takes care of initializing
the Pixman region.
