When a wlr_output add to wlr_output_layout, wlr_cursor will create
wlr_buffer of xcursor for the wlr_output, this behavior depends
wlr_renderer of wlr_output, using assert to ensure renderer is
initialized before wlr_output_layout_add and wlr_cursor_set_buffer/
wlr_cursor_set_xcursor.
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.
If the set_cursor request is used with the same surface, don't call
cursor_output_cursor_reset_image(). That function sends
wl_surface.leave and can cause an infinite feedback loop with some
clients (submitting a LoDPI cursor when the surface leaves an HiDPI
output).
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3669
A client might update the cursor with the same wl_surface as
before, but with a different hotspot. Don't ignore such updates.

There doesn't appear to be any good reason to warp the cursor to
the top-left corner when all outputs are disconnected; it's no more
valid than any other (x,y) point in that case.
The real-world case here is a user with a single external monitor
turning it off (which apparently counts as disconnected depending
on the connection type/hardware). For that user, it's desirable to
have the cursor remain in its original location when the monitor
is turned back on.
It should be considered a bug if a compositor sets a non-finite
cursor position, so fail loudly (in debug builds) if that happens.
The existing check in wlr_cursor_warp_closest() is now redundant,
and would silently hide such bugs, so remove it.
Commit 498f30aad1 changed the logic of
get_mapping() in types/wlr_cursor.c to use updated version of
wlr_output_layout_get_box(). However, the case where c_device isn't NULL
but doesn't have output or geometry mappings wasn't handled properly,
resulting in leaving the output value uninitialized. This commit fixes
`c_device != NULL` branch by returning from the function only when a
mapping is found.

In the case that only one axis received an event, rotating the input can
cause the change to actually happen on the other axis, as far as clients
are concerned.
This commit updates the axes flags to be consistent post-rotation.
Fixesswaywm/sway#4776.
The Wayland protocol specifies output transform rotations to be
counterclockwise and applied to the surface. Previously, wlroots
copied Weston and incorrectly made rotations act clockwise on
surfaces. This commit fixes that.
This change will break compositors which expect transform rotations
to be clockwise, and the rare applications that make use of surface
transforms.
If box->width/height is <= 0, the box doesn't contain any points, and so
there is no closest point. wlr_box_closest_point should return NAN in this
case.
In addition, we need to handle empty boxes in a few other
output-layout-related places, because outputs can have size 0x0 when
they are created or destroyed.
The documentation for wayland-server.h says:
> Use of this header file is discouraged. Prefer including
> wayland-server-core.h instead, which does not include the server protocol
> header and as such only defines the library PI, excluding the deprecated API
> below.
Replacing wayland-server.h with wayland-server-core.h allows us to drop the
WL_HIDE_DEPRECATED declaration.
Frame events group logically connected pointer events. It makes sense to make
the backend responsible for sending frame events, since once the events are
split (ie. once the frame events are stripped) it's not easy to figure out
which events belongs to which frame again.
This is also how Weston handles frame events.

wlr_cursor: make sure the output doesn't have a cursor before
creating a new one
wlr_output_layout: don't emit the "add" event when the output is
already in the layout
