Refactor the scene graph implementation by splitting wlr_scene.c
into multiple focused units: buffer, node, rect and tree. Introduce
corresponding public headers for each component.
This reduces the size and complexity of the core scene file, improves
code organization and makes individual parts of the scene graph easier
to maintain and extend.
As part of this refactor, drop unnecessary pointer indirection when
passing scene trees (e.g. &scene->tree → scene->tree) and update all
call sites accordingly.
No functional changes intended.
Split texture rendering out of wlr_render_pass and introduce a
dedicated wlr_render_texture_pass interface.
Remove the add_texture hook from wlr_render_pass_impl and route
texture rendering through renderer->texture_pass instead.
Split rectangle rendering out of wlr_render_pass and add a dedicated
wlr_render_rect_pass interface.
Remove the add_rect hook from wlr_render_pass_impl and implement
rectangle rendering separately in the pixman, GLES2 and Vulkan
renderers.
The returned fence is not required to be signalled at the earliest
possible time. It is not intended to replace the drm flip event, and is
expected to be signalled only much later
This changes the behavior of wlr_linux_drm_syncobj_surface_v1 to
automatically signal release of previous commits as they are replaced.
Users must call wlr_linux_drm_syncobj_v1_state_add_release_point or
wlr_linux_drm_syncobj_v1_state_signal_release_with_buffer to delay the
signal as appropriate.
Add color_representation to wlr_output_state, holding color
representation metadata about the primary buffer. This can be set
using wlr_output_state_set_primary_color_representation() and a
new enum value WLR_OUTPUT_STATE_COLOR_REPRESENTATION in
wlr_output_state.committed indicates when this data is present.
Also add color-representation to wlr_output, and discard
color-representation in wlr_output_state if it matches what's already
been committed to the output.
Currently we send wl_surface.enter/leave when a surface is hidden
and shown again on the same output. In practice, this happens very
often since compositors like river and sway enable and disable
the scene nodes of surfaces as part of their atomic transaction
strategy involving rendering saved buffers while waiting for
clients to submit new buffers of the desired size.
The new strategy documented in the new comments avoids sending
redundant events in this case.
wlr_box_intersection generates a new box based on the intersection of
two boxes. Often we simply want to know *if* two boxes intersected,
which we can answer much cheaper.
Add wlr_box_intersects, in similar vein as wlr_box_contains_box but
returning true for any overlap.
This allows using the vulkan renderer on platforms that provide all
the necessary Vulkan extensions.
Tested on a Mali G52 platform with Mesa 26.0.0 and 25.3.5, which only
support Vulkan API 1.0.
We'll need to grab textures from there in the next commit.
Also rename it to better reflect what it does: synchronize release
fences after a render pass has been submitted.
When libinput introduces new enum entries, we'd abort or send bogus
events to the compositor. Instead, log a message and ignore the
event.
Keep all enums without a default case so that the compiler warns
when we're missing a case.
Exposing libinput_tablet_tool from libinput allows compositors
to set tool specific configuration options like pressure range
and eraser button behavior.
See 'libinput_tablet_tool_*()' functions which require a
'libinput_tablet_tool' handle:
https://wayland.freedesktop.org/libinput/doc/1.30.0/api/group__config.html
(libinput 1.30.0, latest at the time of writing).
schedule_frame is only called when the client has submitted damage
and a new frame should be rendered immediately. schedule_frame is
not called when the capture client is waiting for the next frame
but hasn't submitted damage.
Sources implementing a rendering loop based on the capture rate
need to know when a capture client is ready to accept a new frame.
Such sources want to trigger a redraw if and only if (1) they are
dirty (their contents have changed) and (2) the capture client is
ready to accept a new frame.
Replace schedule_frame with request_frame, triggered each time a
client sends a capture request. A flag indicates whether the capture
client has submitted damage.
