wl_display holds a lot more than wlr_session needs: wlr_session
only needs to wait for a FD to become readable, but wl_display
provides full access to the Wayland client and protocol objects.
Switch to wl_event_loop to better reflect the above.
While the xdg-shell protocol requires this, it does not yet have
a dedicated error code for invalid titles; this commit makes
wlroots send a generic error instead.
When a texel from the Vulkan format VK_FORMAT_B8G8R8A8_SRGB is read,
the sRGB to linear conversion is applied independently to the R, G,
and B channels; the A channel has no influence on this. However,
DRM_FORMAT_ARGB8888 buffers are, per Wayland protocol, not encoded
in this fashion; one must first unpremultiply the color channels
before doing sRGB to linear conversion. This commit switches to
handling ARGB8888 and ABGR8888 formats using the general fragment
shader conversion from electrical to optical values.
Introduce a per-page-flip tracking struct passed to the kernel
when we request a page-flip event for an atomic commit. The kernel
will pass us back this pointer when delivering the event.
This eliminates any risk of mixing up events together. In particular,
if two events are pending, or if the CRTC of a connector is swapped,
we no longer blow up in the page-flip event handler.

We want to call the outputs updated signal when an output scale or transform
changes. Otherwise helpers like the scene surface helpers will not be
notified of scale changes and not pass them to clients.
Right now this is done "by chance" because we disable all CRTCs
on shutdown. However, we'll stop doing this. Plus, if disabling
a CRTC fails, we don't cleanup properly.
"View" has been cargo-culted from Weston. In Weston, a view is not
even necessarily a toplevel -- it's just a way to draw an arbitrary
somewhere (a surface may be painted at multiple locations
simultaneously). The Weston concept has been misunderstood and then
was carried over to rootston, Sway, and tinywl.
Let's just use the official Wayland wording instead.
Since commit 5567aefb, fixed modes haven't been automatically generated
for custom modes, so the output management implementation needs to be
able to handle them directly. To avoid polluting the mode list, only a
single custom mode can be listed at a time and will be removed when a
fixed mode is set.
