This seems like nothing interesting was done with this. Let's simplify
and allow us some flexibility in the future.

Default to texture instead of destination_box geometry.

This will display red translucent rectangles on the screen regions that
have been damaged. These rectangles will fade out over the span of 250
msecs. If the area is damaged again while the region is fading out,
the timer is reset.
Let's also disable direct scan out when this option is enabled, or else
we won't be able to render the highlight damage regions.

Instead iterate over wlr_scene_buffer
|
|
We will need this for surface emulation on buffers.

wlr_scene_buffer

Let's also change the name of the function. Motivation [1].

This function sidesteps damage tracking and output awareness on
buffers/surfaces. This function isn't a great fit for the API.
Let's also inline the function and simplify it.
|
|
There were a couple places this was missing
- on mode change of an output. If the resolution changes for example
nodes may fall out of the view.
- on commits on an output for scale or transform changes
- when the transform of a buffer is changed. If the dest size is not
set, the buffer may have been rotated potentially changing its size
if the buffer width != height
|
|
When we destroy a scene buffer, let's make sure that we call
output_leave signals before we finish the node which will call destroy
listeners.

This is useful to emulate an unmapped surface.

Ensures there is no field left to its previous undefined value after
calling an init function.

This reverts commit 3db1bcbe641b407b9f5c9e5d0a012b45aa2c6cb7.
Since [1], importing buffers as textures before wlr_renderer_begin isn't
necessary anymore.

This helper behaves similar to the xdg_shell helper, and additionally
provides a little assistance for positioning and exclusive_zone
management.
|

The wlroots APIs currently don't allow importing/uploading a buffer
during rendering operations. Scene-graph buffer nodes need to turn
their wlr_buffer into a wlr_texture at some point. It's not always
possible to do so at wlr_scene_buffer creation time because the
scene-graph may have zero outputs at this point, thus no way to
grab a wlr_renderer.
Instead, add scene-graph buffers to a pending list and try to import
them in wlr_scene_output_commit.

This commit renames map/unmap listeners to clarify that they handle
subsurface events, and ensures the node is always destroyed before
the subsurface.
Without this patch, wl_list_remove() would operate on listener links in
already freed memory. glibc is usually lenient to bugs like this, but
musl isn't.

Some clients (e.g. mpv, Firefox) request a new wl_surface.frame
callback without damaging their surface. When this happens,
schedule a new output frame.

This helper automates sending presentation feedback to clients based on
the primary output of scene surfaces.
|
|
This doesn't work if scene outputs are not used as the primary output of
scene surfaces will always be NULL.
Therefore, take a wlr_scene_output instead of separate wlr_scene and
wlr_output arguments and rename the function to
wlr_scene_output_send_frame_done().
The actual behavior of the function is unchanged.
|
|
|
|
This allows compositors to avoid sending multiple frame done events
to a surface that is rendered on multiple outputs at once. This may
also be used in the same way for presentation feedback.

Before this commit, it would keep the node at the top or make it second-
topmost.
|
|
This allows getting a wlr_scene_output from a wlr_output. Since an
output can only be added once to a scene-graph there's no ambiguity.
This is useful for compositors using wlr_scene_attach_output_layout:
the output layout integration automatically creates a scene-graph
output for each wlr_output added to the layout.
|
|
If the surface has a source box set, use that.
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3172

This allows compositors to easily add an xdg_surface to the
scene-graph while retaining the ability to unconstraint popups
and decide their final position.
Compositors can handle new popups with the wlr_xdg_shell.new_surface
event, get the parent scene-graph node via wlr_xdg_popup.parent.data,
create a new scene-graph node via wlr_scene_xdg_surface_tree_create,
and unconstraint the popup if they want to.

This is only called from one function.
To destroy the wlr_scene_subsurface_tree from elsewhere, callers
can destroy the scene-graph node returned by
wlr_scene_subsurface_tree_create instead (just like a compositor
would do). subsurface_tree_handle_surface_destroy does exactly this.
Inlining avoids calling subsurface_tree_destroy by mistake.
|
|
Check if only a single node intersects with the output viewport
and all of its properties match. In this case, attempt direct
scan-out.
|
|
This allows compositors to more easily implement sending
wl_surface.frame callback done events.
|
|
|
|
These are very common operations for compositors (including tinywl)
to perform.
