If the default queue is being destroyed, the client is disconnecting
from the wl_display, so there is no possibility of subsequent events
being queued to the destroyed default queue, which is what this warning
is about.
Note that interacting with (e.g., destroying) a wl_proxy after its
wl_display is destroyed is a certain memory error, and this warning will
indirectly warn about this issue. However, this memory error should be
detected and warned about through a more deliberate mechanism.

Detect when we are trying to add an event to a destroyed queue,
and abort instead of causing a use-after-free memory error.
This situation can occur when an wl_event_queue is destroyed before
its attached wl_proxy objects.

With wl_shm_buffer_ref_pool(), it's possible for a wl_shm_pool
to outlive its wl_resource. We need to be careful not to access
wl_shm_pool.resource if it's been destroyed.

Most compositors send the wl_data_offer.source_actions event before the
wl_data_device.enter event, i.e. after creation of the data offer. This
contradicts to the wayland spec.
On the other hand, it's reasonable to send all the information useful to
the client before the enter event, rather than send mime types before the
enter event and source actions (that don't depend on drop target) after
the enter event.
On the client side, toolkits such as Qt and GTK already expect to see the
source actions before receiving the enter event.
Given all of that, this change adjusts the spec to match the behavior
observed in the compositors in the wild.

Attaching a buffer with interface version 5 requires clients to pass
zero to x and y but it still affects the pending surface state.
Attaching a buffer after a request to offset therefore sets the pending
x and y to zero. The intent of version 5 was to allow exactly this
sequence of requests to work so let's just make sure the protocol
actually spells it out.

This event adds the physical direction of the axis motion, relative to the
axis event we get. Right now, when natural scrolling is enabled things like
virtual volume sliders move the wrong way round.
By adding the axis motion direction, we can have toolkits swap the scroll
direction for applicable widgets, getting the right behavior on all widgets.

Same as the new wl_surface.preferred_buffer_scale event but for
transform.
No version bump needed since the previous commit did that.
Signed-off-by: Simon Ser <contact@emersion.fr>
Right now, clients need to bind to wl_output globals, listen to wl_output.scale,
listen to wl_surface.enter/leave, pick the highest scale factor.
This is an issue because it breaks Wayland's "policy, not mechanism" motto.
Clients take the decision of which scale to use depending on the outputs they're
on, compositors have no say in this (apart from faking output events, which
isn't great).
This commit introduces a new wl_surface.preferred_buffer_scale event to allow
compositors to directly indicate the preferred scale factor for each surface.
This unlocks features which require dynamically changing the scale such as:
- Accessibility features such as screen magnifier
- In a VR environment, render surfaces close to the eye at a higher scale
- HiDPI screenshots on LoDPI screens

Unfortunately, the actual package name is hardcoded, meaning that to
