Simon Ser b25759cd20 scene: drop default case in wlr_scene_node_at
This allows the compiler to error out if we haven't enumerated all
of the cases. This is useful to avoid a missing implementation when
adding a new node type.

Kirill Primak 0e2d369106 xdg-surface: simplify configure mechanism
This commit removes any checks whether a configure will change anything
and makes configures be sent unconditionally. Additionally, configures
are scheduled on xdg_toplevel.{un,}set_{maximized,fullscreen} events.

Kirill Primak b72a217fcc xdg-toplevel: refactor configure/state flow
Previously, `wlr_xdg_toplevel` didn't follow the usual "current state +
pending state" pattern and instead had confusingly named
`client_pending` and `server_pending`. This commit removes them, and
instead introduces `wlr_xdg_toplevel.scheduled` to store the properties
that are yet to be sent to a client, and `wlr_xdg_toplevel.requested`
to store the properties that a client has requested. They have different
types to emphasize that they aren't actual states.

Simon Ser 4e7a8707cc buffer: add data_ptr access flags
This allows callers to specify the operations they'll perform on
the returned data pointer. The motivations for this are:

- The upcoming Linux MAP_NOSIGBUS flag may only be usable on
  read-only mappings.
- gbm_bo_map with GBM_BO_TRANSFER_READ hurts performance.

When providing non-zero layout-local coordinates to

values: when giving 42,42 the viewport's position would be set to
-42,-42.

Simon Ser 04304c322e output-damage: fix damage on modeset
On modeset wlr_output will internally allocate a buffer. The
backend will emit a "mode" output event, then wlr_output will
emit a "commit" event.

wlr_output_damage handles the "mode" event by damaging the whole
output, and then handles the "commit" event. However the commit
event has a buffer, so wlr_output_damage rotates the damage in its
ring buffer, thinking the compositor has rendered a frame. The
compositor hasn't rendered a frame, what wlr_output_damage sees is
the internal wlr_output black buffer used for the modeset.

Let's fix this by damaging the whole output in the "commit" event
handler if the mode has changed. Additionally, damage the whole
output after rotating the damage ring buffer.

Devin J. Pohly 9ed16e39fa scene: replace surface_at() with node_at()
With the addition of a non-surface node type, it was unclear how such
nodes should interact with scene_node_surface_at().  For example, if the
topmost node at the given point is a RECT, should the function treat
that node as transparent and continue searching, or as opaque and return
(probably) NULL?

Instead, replace the function with one returning a scene_node, which
will allow for more consistent behavior across different node types.
Compositors can downcast scene_surface nodes via the now-public
wlr_scene_surface_from_node() if they need access to the surface itself.

Kirill Primak 109405729b surface: fix place_below handling
If a subsurface is being placed below a subsurface right above it, this

inserted into itself, breaking parent's pending subsurface list.

This commit separates finding the requested node and getting it's `prev`
field, fixing the issue.

Isaac Freund 3364eec07e layer-shell: replace close() with destroy()
The protocol specifies that all requests (aside from destroy) are
ignored after the compositor sends the closed event. Therefore,
destroying the wlroots object and rendering the resource inert

compositors.

Quantum 456c6e2279 viewporter: remove crop and scale state upon destruction
According to the viewport protocol, upon wp_viewport::destroy():

> The associated wl_surface's crop and scale state is removed.
> The change is applied on the next wl_surface.commit.

Therefore, wp_viewport_destroy(viewport) should remove all viewport state.

Currently, wlroots does not remove the crop and scale state. Instead, a
client must do:

    wl_fixed_t clear = wl_fixed_from_int(-1);
    wp_viewport_set_source(viewport, clear, clear, clear, clear);
    wp_viewport_set_destination(viewport, -1, -1);
    wp_viewport_destroy(viewport);

This commit adds the necessary logic into viewport_destroy and makes
wlroots comply with the protocol.

Simon Ser 8afb4d8bf0 buffer: re-use wlr_shm_client_buffer
The first time wlr_buffer_from_resource is called with a wl_buffer
resource that originates from wl_shm, create a new
wlr_shm_client_buffer as usual. If wlr_buffer_from_resource is called
multiple times, re-use the existing wlr_shm_client_buffer.

This commit changes how the wlr_shm_client_buffer lifetime is managed:
previously it was destroyed as soon as the wlr_buffer was released.
With this commit it's destroyed when the wl_buffer resource is.

Apart from de-duplicating wlr_shm_client_buffer creations, this allows
to easily track when a wlr_shm_client_buffer is re-used. This is useful
for the renderer and the backends, e.g. the Pixman renderer can keep
using the same Pixman image if the buffer is re-used. In the future,
this will also allow to re-use resources in the Wayland and X11 backends
(remote wl_buffer objects for Wayland, pixmaps for X11).

Simon Ser b934fbaf04 seat: add wlr_seat_touch_{send,notify}_frame
The wl_touch.frame event is used to group multiple touch events
together. Instead of sending it immediately after each touch event,
rely on the backend to send it (and on the compositor to relay it).

This is a breaking change because compositors now need to manually
send touch frame events instead of relying on wlr_seat to do it.

Simon Ser a48e569d38 output-damage: fix output swapchain handling
When wlr_output.swapchain is used instead of the backend's, the
buffer_type will be set to SCANOUT even if wlr_output_attach_render
has been called. This tricks wlr_output_damage into thinking the
whole output needs to be repainted.

Workaround this issue by forcing buffer_type to RENDER when the
output has a back-buffer set.

Will clean all of that up when removing the precommit event handler
altogether.

This commit fixes damage tracking on the Wayland, X11 and headless
backends.

Simon Ser c2bd63c186 output: detach buffer from renderer before commit
Right now we rely entirely on implicit sync for synchronizing
access to GPU buffers. Implicit sync works by setting
synchronization points on the buffer in writers, and letting
readers wait on these sync points before accessing the buffer.

With OpenGL, sync points are created using functions such as
eglSwapBuffers or glFlush. If none of these special functions
are called, no sync point will be created and readers will
potentially access a buffer that hasn't finished rendering yet.

In the context of wlroots, OpenGL is the writer and the backend
(KMS or parent Wayland/X11 session) is the reader. After we're
done rendering a frame, and before passing that frame to the
backend, we need to call glFlush.

glFlush is called when the buffer is detached from the renderer.
This is a task done by output_clear_back_buffer. So let's call
this function before invoking the impl->commit hook, instead of
calling it after.

All of this is maybe a little tricky to get right with the
current renderer_bind_buffer API. The new
wlr_renderer_begin_with_buffer API is much better, because glFlush
is called on wlr_renderer_end, so it's more intuitive.

Simon Ser e5b5592a95 render: remove wl_drm support from wlr_renderer
Everything needs to go through the unified wlr_buffer interface
now.

If necessary, there are two ways support for
EGL_WL_bind_wayland_display could be restored by compositors:

- Either by using GBM to convert back EGL Wayland buffers to
  DMA-BUFs, then wrap the DMA-BUF into a wlr_buffer.
- Or by wrapping the EGL Wayland buffer into a special wlr_buffer
  that doesn't implement any wlr_buffer_impl hook, and special-case
  that buffer type in the renderer.

This allows renderers to choose between implementing the old

Simon Ser 9e58301df7 surface: allow placing subsurfaces below parent
Prior to this commit, subsurfaces could only be placed above their
parent. Any place_{above,below} request involving the parent would
fail with a protocol error.

However the Wayland protocol allows using the parent surface in the
place_{above,below} requests, and allows subsurfaces to be placed
below their parent.

Weston's implementation adds a dummy wl_list node in the subsurface
list. However this is potentially dangerous: iterating the list
requires making sure the dummy wl_list node is checked for, otherwise
memory corruption will happen.

Instead, split the list in two: one for subsurfaces above the parent,
the other for subsurfaces below.

Tested with wleird's subsurfaces demo client.

Simon Ser 76f51a949f xdg-activation-v1: add token timeout
There isn't always a good time to prune old tokens. Compositors
which only implement a "give focus on activation" logic can prune
tokens on focus change. However other compositors might want to
implement other semantics, e.g. "mark urgent on activation". In this
case a focus change shouldn't invalidate other tokens.

Additionally, some tokens aren't necessarily tied to a seat.

To avoid ending up with an ever-growing list of tokens, add a timeout.

Yuya Nishihara 8008d21f5b virtual_keyboard: Emulate key release events on destroy

This is another attempt to fix #2034 and the following sway issue:

https://github.com/swaywm/sway/issues/6254

Note that we have other key repeating issues in sway, which aren't addressed
by this patch. Since the virtual keyboard itself isn't destroyed when the
keyboard grab is destroyed, we'll probably need some trick to reset the state
of the corresponding virtual keyboard when the grab is released.

Simon Ser e8df7c367a linux-dmabuf-v1: split params and buffer
Previously, the same struct was used for linux-dmabuf-v1 params

a wlr_dmabuf_v1_buffer could either be still being constructed, or
be a complete buffer.

Introduce a separate wlr_linux_buffer_params_v1 struct for buffer
params still being constructed. Once the params are complete (ie.
once the create request is sent), the params struct is destroyed
and the buffer struct is created.
