Everything implementing `AsGlowRenderer` implements `Renderer` and various
other traits, and by making `AsGlowRenderer` depend on these trait,
things requiring `AsGlowRenderer` can avoid listing those traits as
well.
Looks like implied trait bounds still won't work for the
`Self::TexutureId` and `Self::Error` requirements? So those are not
included here.

This reverses the part of
ca00df0b37 that made it
only try import on the advertised GPU. But this version avoids
initializing an EGL context simply to re-check the supported texture
formats.
The logic `age_for_buffer` used seems to be a misinterpretation of the
protocol.
The wording is a little unclear, but it seems tracking buffer age is the
responsibility of the client, and the client is required to accumulate
damage and pass it in `damage_buffer`.
Our clients initially weren't doing that correctly. I updated
xdg-desktop-portal-cosmic to use `damage_buffer` after testing on
wlroots, and cosmic-workspaces was recently updated as well.
The important change here is that we now apply the additional damage
first, instead of using `.extend()` to add it after other elements. This
is important since `OutputDamageTracker` will ignore our damage elements
if there are behind an element with an opaque region.
This also makes things a bit simpler, especially `take_screencopy_frames()`,
which no longer needs a mutable references to extend then truncate.
The implementation of `OutputDamageTracker` isn't entirely clear, but as
far as I can tell this is intended to work, and it seems to work in some
testing.
This doesn't change much, since the Smithay implementation is based on
the `cosmic-comp` version, but made more generic. We provide our own
implementation for our workspace capture protocol, but otherwise Smithay
handles the boilerplate now.
This should not cause any change in behavior.
Previously we ignored when we had no output configuration
**and** failed to apply the automatically created one.
This leads to two problems:
- If this happens on startup, we end up with no outputs being added to the shell and we quit.
- If this happens later, we might end up in an inconsistent state, where the shell thinks we have an output, when it didn't light up for similar reasons.
Thus `read_outputs` is failable and handling that very much depends on
the where is was called from, because `read_outputs` doesn't know what
configuration was active before.
Thus make it failable and provide useful mitigations everywhere
possible:
- Try to enable just one output in case we fail on startup.
- Don't enable any additional outputs, when we fail on hotplug.
- Log the error like previously in any other case (and come up with more
mitigations, once we understand these cases better).
