needs_frame is for backends to trigger frames for reasons that
compositors couldn't see coming. schedule_frame is freaky and I want to
remove it. These protocols aren't backends but in this case they're
close enough, so switch to needs_frame.

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);

Without a round in this case the damage region is translated to truncated coordinates, potentially
misplacing it relative to the actual position of that region in the output buffer.
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.
Now that role objects are stored as resources, we can distinguish
the inert object case from it being destroyed by the client:
- When the resource is destroyed by the client, role_resource == NULL
- When the resource is made inert, role_resource != NULL but its
user_data is NULL
Recently it has come up that someone wants to re-use part of
wlroots in their own project. The standard procedure is to copy
over the license text and copyright lines.
Let's make it clear that the wlroots copyright is held by all
wlroots contributors, and that the license file comes from the
wlroots project.
See [1] for more details.

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.
Stop using wlr_output_cursor_set_image() because it's getting
dropped. Instead, use wlr_output_cursor_set_buffer().
This mirrors what wlr_output_cursor_set_image() is doing
under-the-hood.
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.
By adding a sent_feedback bool into the list entry that we can mutate
we no longer need to maintain this `sent_direct_scanout_feedback` variable.
sent_feedback will also be useful for output layers.
