An output layout consists of a mapping of outputs to their position in a global
coordinate system that usually cooresponds to the output position in physical
space in front of the user.
Add an example that allows configuration of an output layout and demonstrates
its boundaries with a bouncing image.
- xdg toplevel configure can be called with 0 width/height,
in that case we are free to do as we like (so do nothing)
- need a display roundtrip after everything is setup but before
we start attaching buffers to the surface
Note that this does not go on to the next backend, because
attempt_wl_backend does not check if we have any output created.
We cannot test simply because (right now) a run of our examples will go
in this function twice, the first of which will (rightly?) return no
display but needs to return backend creation success.
This runs through events pending at init on initialization so we can
tell if some devices are available.
Note that with the way wlr_device_lists is managed, this checks that
there is at least one device we handle - it doesn't have to be a
keyboard, but there is at least a mouse or tablet_pad or something
that we care about.
Instead of failing inconditionally it might be better to leave the
decision to the user, e.g. add a "backend_has_devices" function to
call later.
(Tested by moving /dev/input off)
Fixes#24.
- Implement xdg_shell_destroy and use it at the right place
(impl->destroy is never called)
- Remove wl_global_destroy for now, something is missing with the
display/registry_resource_list
Also:
- rename wlr_xdg_shell_v6_init to create as that is what it does
- free wlr_xdg_shell on failure to create wl_global, the struct
is not initialized enough to call destroy at that point
Keep track of the scale of the buffer set by surface.set_buffer_scale.
Calculate the height and width of the texture from the buffer depending on the
scale when it is attached.
Use buffer damage to determine the damage of the buffer when flushing damage.
Convert surface damage to buffer damage and union to the surface buffer_damage
prior to flushing damage.
