If these aren't provided by the backend, allocate a swapchain for the
output.

Simon Ser 4d603826c8 output: add get_primary_formats to interface
This function returns the set of formats the backend can use for the
primary buffer. It can be used to allocate a buffer suitable for
scan-out.

Simon Ser 7c26345826 buffer: introduce wlr_shm_client_buffer
Introduce wlr_shm_client_buffer, which provides a wlr_buffer wrapper
around wl_shm_buffer.

Because the client can destroy the wl_buffer while we still are using
it, we need to do some libwayland tricks to still be able to continue
accessing its underlying storage. We need to reference the wl_shm_pool
and save the data pointer.

Simon Ser 38ba5881a0 buffer: replace get_data_ptr with {begin,end}_data_ptr_access
This new API allows buffer implementations to know when a user is
actively accessing the buffer's underlying storage. This is
important for the upcoming client-backed wlr_buffer implementation.

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.

Simon Ser b86a0c8d8f backend/drm: move cursor fields to wlr_drm_connector
Doesn't make a lot of sense to split the cursor fields between
wlr_drm_plane and wlr_drm_connector. Let's just move everything to
wlr_drm_connector.

Simon Ser 2b0a1aeed5 output: take a wlr_buffer in set_cursor
Instead of passing a wlr_texture to the backend, directly pass a
wlr_buffer. Use get_cursor_size and get_cursor_formats to create
a wlr_buffer that can be used as a cursor.

We don't want to pass a wlr_texture because we want to remove as
many rendering bits from the backend as possible.

Simon Ser 6430230d1f render: add wlr_renderer_begin_with_buffer
This allows compositors to choose a wlr_buffer to render to. This

Tudor Brindus ae2f3ecb68 xwm: implement _NET_CLIENT_LIST_STACKING
This property is present on all modern X11 instances. The nonpresence of
it requires applications to fall back to XQueryTree-based logic to
determine stacking logic (e.g., to determine what surface should get
Xdnd events).

These code paths are effectively untested nowadays, so this makes it
more likely for wlroots to "break" applications. For instance, the
XQueryTree fallback path has been broken in Chromium for the last 10
years.

It's easy enough to maintain this property, so let's just do it.

Fixes #2889.

Simon Ser abf527b075 render/gles2: fix texture cleanup on destroy
When importing a DMA-BUF wlr_buffer as a wlr_texture, the GLES2
renderer caches the result, in case the buffer is used for texturing
again in the future. When the wlr_texture is destroyed by the caller,
the wlr_buffer is unref'ed, but the wlr_gles2_texture is kept around.
This is fine because wlr_gles2_texture listens for wlr_buffer's destroy
event to avoid any use-after-free.

However, with this logic wlr_texture_destroy doesn't "really" destroy
the wlr_gles2_texture. It just decrements the wlr_buffer ref'count.
Each wlr_texture_destroy call must have a matching prior
wlr_texture_create_from_buffer call or the ref'counting will go south.

Wehn destroying the renderer, we don't want to decrement any wlr_buffer
ref'count. Instead, we want to go through any cached wlr_gles2_texture
and destroy our GL state. So instead of calling wlr_texture_destroy, we
need to call our internal gles2_texture_destroy function.

Simon Ser c82f37542d backend/headless: use common renderer and allocator
Instead of managing our own renderer and allocator, let the common
code do it.

Because wlr_headless_backend_create_with_renderer needs to re-use
the parent renderer, we have to hand-roll some of the renderer
initialization.

Simon Ser 7ec5bf6b10 backend: introduce wlr_backend_finish
This new functions cleans up the common backend state. While this

the renderer and allocator in upcoming patches.

Simon Ser f6ba26ff58 render/gles2: implement texture_from_buffer
Make it so wlr_gles2_texture is ref'counted (via wlr_buffer). This
is similar to wlr_gles2_buffer or wlr_drm_fb work.

When creating a wlr_texture from a wlr_buffer, first check if we
already have a texture for the buffer. If so, increase the
wlr_buffer ref'count and make sure any changes made by an external
process are made visible (by invalidating the texture).

When destroying a wlr_texture created from a wlr_buffer, decrease
the ref'count, but keep the wlr_texture around in case the caller
uses it again. When the wlr_buffer is destroyed, cleanup the
wlr_texture.

Simon Ser 9d55f712e3 render: introduce wlr_texture_from_buffer
This adds a a function to create a wlr_texture from a wlr_buffer.

The main motivation for this is to allow the renderer to create a
single wlr_texture per wlr_buffer. This can avoid needless imports
by re-using existing textures.

Simon Ser 485ecc11a6 backend/drm: remove wlr_drm_crtc.pending_modeset

Simon Ser 1a9701cd7c backend/drm: take wlr_output_state as arg in commit callers

Simon Ser 8f90d7f8f5 backend/drm: take wlr_output_state as arg in crtc_commit
Stop assuming that the state to be applied is in output->pending in
crtc_commit. This will allow us to remove ephemeral fields in
wlr_drm_crtc, which are used scratch fields to stash temporary
per-commit data.

Simon Ser 619a975025 render: remove wlr_ prefix from wlr_renderer_autocreate_with_drm_fd

Simon Ser 24fde77c62 buffer: add format param to get_data_ptr
Allow wlr_buffer_impl.get_data_ptr to return a format.

This allows the Pixman renderer to not care about get_dmabuf/get_shm,
and only care about get_data_ptr. This will also help with [1], because
client wl_shm buffers can't implement get_shm.
