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 01e0f51fad backend/drm: introduce drm_plane_pick_render_format
This is a new helper function to pick a render format suitable for

surface.

Simon Ser 6430230d1f render: add wlr_renderer_begin_with_buffer
This allows compositors to choose a wlr_buffer to render to. This
is a less awkward interface than having to call bind_buffer() before
and after begin() and end().

this is not allowed.

Simon Ser ce3e819b33 backend: stop using renderer to get the buffer type
When picking a format, the backend needs to know whether the
buffers allocated by the allocator will be DMA-BUFs or shared
memory. So far, the backend used the renderer's supported
buffer types to guess this information.

This is pretty fragile: renderers in general don't care about the
SHM cap (they only care about the DATA_PTR one). Additionally,
nothing stops a renderer from supporting both DMA-BUFs and shared
memory, but this would break the backend's guess.

Instead, use wlr_allocator.buffer_caps. This is more reliable since
the buffers created with the allocator are guaranteed to have these
caps.

Simon Ser 766a24fa77 render/allocator: add wlr_allocator.buffer_caps
This allows users to know the capabilities of the buffers that

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.

Because wlr_headless_backend_create_with_renderer needs to re-use

initialization.

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 101b9a193d render/egl: query and display EGL driver name
GL_RENDERER typically displays a human-readable string for the name
of the GPU, and EGL_VENDOR typically displays a human-readable string
for the GPU manufacturer. EGL_DRIVER_NAME_EXT should give the name of
the driver in use.

Yuya Nishihara 8008d21f5b virtual_keyboard: Emulate key release events on destroy
According to libinput, release events are generated when device is unplugged,
and libinput copies this behavior for device removal. Let's do the same for
our virtual keyboard.

8f846a41fa

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.

Changing the argument type to an unsigned type is an effective merge of
