Saving the old context and immediately making our own context
current is a common pattern. Let's make it easier to do.
No functional change, just refactoring.
For XWayland surfaces that start maximized, it's best to send an initial
Configure event to set the size of the surface before mapping it. This
reduces visual glitches since the application sees the correct maximized
size when performing its initial layout and drawing.
wlroots surfaces emit their first "map" event after the XWayland window
has already been mapped and the first frame has been drawn & committed.
This is too late to send the initial Configure event.
So, add a new "map_request" event which is emitted immediately before
telling XWayland to map the window. Compositors can connect to this
event to send the initial Configure event to an XWayland app based on
its requested maximized (or fullscreen) state.
Compositors should not place anything visually on the screen at this
point but rather wait until the "map" event as before.
On startup, we fetch the previous MODE_ID blob ID so that
compositors can keep using the previous mode if they want to.
However, that blob doesn't belong to us, it belongs to the
previous DRM master. As a result, we get an error when trying to
destroy it.
Fix this by tracking whether the blob belongs to us or not.

This implements the new ext-foreign-toplevel-list-v1 protocol [1].
Implemented analog to the zwlr-foreign-toplevel-management-v1 implementation.
The additional _ext_ in the names was added to avoid name collisions.

Compositors now are expected to wait for an initial commit by checking
wlr_xdg_surface.initial_commit on every surface commit and send
(schedule) configure events manually.
Since we only use the backend capabilities here we can simply pass
them in directly. This allows other locations to create an allocator
even if they don't have a backend. They can simply specify the caps
they want instead.
Some opaque pixel formats (nv12, p010) require per-plane bytes_per_block
info. However, it doesn't make sense to store them in
wlr_pixel_format_info, as they will never be useful (currently, this
info is used for shm, which doesn't have a concept of multi-planar
buffers.)
Let's define a separate array and function for determining whether a
pixel format has alpha.
This makes it easy for compositors to handle situations where the
DRM or libinput backend becomes unavailable. Compositors can listen
the destroy event of the multi backend returned by
wlr_backend_autocreate() and decide what to do.
wlr_output.refresh is populated by core wlr_output, and thus will
be zero for a custom mode with an unset refresh rate.
Save the refresh rate from the drmModeModeInfo in wlr_drm_connector
instead.

A lot of protocols extend the wl_surface state. Such protocols need
to synchronize their extended state with wl_surface.commit and
cached states. Add a new utility for this purpose.
This is the last of a set of commits which ensures that both textures
and render buffers can be accessed through _UNORM and _SRGB image
views. While _UNORM image views are not yet used for 8-bpc image
formats, they will be needed in the future to support color transforms
for both textures and render buffers.
Sadly, the new API is not backwards compatible with the old API. Since
we have already switched all users in wlroots to the new API compositors
are already practically mandated to implement the new API. Let's get rid
of the old one since there is no point.
It turns out we forgot about the function declaration in the header.
Also some docs were still referring to that function.
Move the wlr_output_attach_render() docs to
wlr_output_begin_render_pass().
These comments were a bit misleading:
- "GL_TEXTURE_2D == mutable": not really, imported non-external-only
DMA-BUFs would also use this target, but are not mutable.
- "Only affects target == GL_TEXTURE_2D": same here.
- "If imported from a wlr_buffer": not really, would be NULL if
imported from a shm wlr_buffer.
Adjust these comments to better reflect reality and adjust the check
in gles2_texture_update_from_buffer().
We can double import a dmabuf if we use it as a texture target and
a render target. Instead, let's unify render targets and texture dmabuf
imports to use wlr_gles2_buffer which manages the EGLImageKHR
This adds an alternate way to use wlr_damage_ring without the
concept of buffer age. Buffer age is a concept inherited from EGL
but there is no real reason why we should continue to use that in
wlroots. Instead, use wlr_buffer pointers.
Eventually, we should be able to remove the buffer age based
functions.
