This new interface in libva2 offers a cleaner way to export surfaces
which can then be imported to EGL. In particular, this works with
the Mesa driver, so we can have proper playback without a pointless
download and upload on AMD cards.
This change does nothing with libva1, and will fall back to the
libva1 interface (vaDeriveImage() + vaAcquireBufferHandle()) if
vaExportSurfaceHandle() is not present.

Rename --stats to --load-stats-overlay and add an entry to options.rst

Previously multiple timers were used to realize oneshot, toggling
(redrawing) and page keybindings. The oneshot case in particular also
relied on mp.osd_message to display text only for a given duration.
This was changed to only use one timer in total now. Because now each
case has a defined "start" and "end" point (including oneshot)
mp.set_osd_ass() can be used to print stats as well. This is currently
optional and has to be activated using the config option
persistent_overlay=true.
One shortcoming: oneshot and toggling are mutual exclusive right now.
Previously you could enter toggling while oneshot stats were shown,
this is not possible anymore to reduce the number of cases to be
considered. This can be added later on if desired.
It used a bad heuristic that got even worse/less reliable with recent
changes in mpv. In fact, it's not reliable at all.
Watch out for dropped frames instead. That's a useful indicator.
Previously I could trigger a bug with intense button mashing, however,
was unable to reproduce it and therefore debug it.
This change now seems to be resilient against button mashing, let's hope
it really is.
Please note that the latest version of this script needs a very recent
version of mpv (from yesterday, to be precise, see the readme).
For older versions, please go to "releases".
HOW IT WORKS:
While the stats are visible (i.e. text is printed to the OSD) a
subsequent click on a numeric key (1, 2, ...) will display the
corresponding "page".
This works no matter if the stats are toggled or just shown as a single
invocation. In case of a single invocation, the newly displayed page
will be shown for the full duration again.
The selected page will be remembered (not persistantly though).
So far, only 3 pages are available.
1: the default page, stats as they used to be
2: extensive VO performance stats (to be redesigned/changed soon)
3: dummy
In the future, many more pages are possible.
Implementation is likely to change again (functionality will stay
the same). A new timer had to be introduced to remove the forced
keybindings in the oneshot case. The toggle case can remove them without
a timer. Ensuring that each mode won't remove timers of the other mode
didn't really turn out neat.
Therefore, I intend to change this again, maybe by merging the
oneshot case into the toggle case.
Due to the large amount of per-pass data, the function takes a parameter
indicating whether or not to print a simplified view instead.
The overall intent is to print the simplified view for now, but supposed
printing the full view on a dedicated "tab" (or extra view type), and as
such, `o.print_perfdata_passes` will go away again. I've only introduced
it for now so users can play around with this functionality if they want
to, until Argon- gets around to implementing stats "tabs".
Previously, we used a property and when it was unavailable we assumed it
doesn't exist before assuming it really is just unavailable. This lead
to unnecessarily falling back to deprecated properties which made mpv
print deprecation warnings.
Now we can really check if a property is not known to mpv.
The alternative would've been to check the error part of mp.get_property
and perform string comparisons on the returned error message.
Not sure if supporting old mpv versions is actually worth it though.

Both come with graphs enabled by default.
They can be disabled using the options plot_vsync_ratio and
plot_vsync_jitter (see the readme regarding customization).
In case both graphs are deactivated the ratio and jitter properties will
be printed on the same line to save some space.
One more user-visible/noticeable change: the maximum used to scale the
values for each graph is no longer calculated each time the stats are
shown but instead when collecting the data. This means the maximum
can actually be higher than all values currently present in a graph's
data buffer. This makes it easier to judge a graph's values, especially
since as we have no axis labels.
To prevent high values staying max forever graph data buffers are
cleared when toggling (can be disabled). It was never useful to
keep old data and simply append newer data (with a time skip) anyway.
This used to be the case, I'm not sure when it changed.
The current way of 'hiding' it in case of 0 is not exactly
good and relies on the OSD representation. It could be done
better by querying the video-sync-active property but that would
require querying yet one more thing...
Added to mpv in commit a14f9249. Simply shown after the gamma curve if
available, since it's semantically attached to it.
Also regroup some of the colorimetry options to make this fit (and for
them to make more sense)
