The decay rate of the audio meters can now be selected in the audio
settings. The values are:
- "Fast" (OBS default, 40 dB / 1.7s)
- "Medium" (Type I PPM, 20 dB / 1.7s)
- "Slow" (Type II PPM, 24 dB / 2.8s)

With the "instant-replay.lua" script, it would only play the last replay
buffer saved, meaning the user would have to save a replay with the
replay buffer hotkey, and then press the "Play Last Replay" hotkey to
play the last replay buffer.
Instead, combine the two and make the script save the replay
automatically first, and then play it back as soon as it's available.
This makes it actually qualify as an "instant replay" script, as its
name implies.
Before the new volume meters were implemented, the meter would flash red
if the audio was clipping. This functionality was removed when the
meters were changed, whether intentionally or unintentionally, and this
patch puts that functionality back in. If clipping occurs, the meters
will be fully colored with the foregroundErrorColor value while the
clipping is occurring.
Due to reports that the bandwidth test is randomly causing community
strikes on Youtube (likely due to bad automatic detection), the
bandwidth test will be disabled for Youtube until the Youtube API is
implemented.
Fixes an issue where text would not have language glyph fallback if
another language would used. This problem still needs a solution on
linux/mac (and preferably a fix for language glyph fallbacks when using
freetype 2 in general).
The click to select scenes follows the same rules
as the main UI. The double click respects the option
under Settings -> General -> Studio -> Transition
to scene when Double Clicked.

Default channel layout for 4 channels is 4.0 in FFmpeg.
Replacing quad with 4.0 will improve compatibility since FFmpeg has
better support of its default channel layouts.
The following features have been added to the audio-meters:
* Stereo PPM-level meter, with 40 dB/1.7s decay rate.
* Stereo VU-level meter, with 300 ms integration time.
* Stereo Peak-hold meter, with 20 second sustain.
* Input peak level color-squares in front of every meter.
* Minor-ticks for each dB.
* Major-ticks for every 5 dB.
* Meter is divided in sections at -20 dB and -9 dB.
The ballistic parameters chosen here where taken from:
* https://en.wikipedia.org/wiki/Peak_programme_meter (SMPTE RP.0155)
* https://en.wikipedia.org/wiki/VU_meter
In the rework I have removed any ballistic calculations from
libobs/obs-audio-controls.c making the calculations here a lot more
simple doing only MAX and RMS calculations for only the samples in
the current update. The actual ballistics are now done by just
the UI/volume-control.cpp because ballistics need to be updated
based on the repaint-rate of the user-interface.
The dB to pixel conversion has been moved from
libobs/obs-audio-controls.c to UI/volume-control.cpp as well to reduce
coupling between these two objects, especially when implementing the
major- and minor-ticks and the sections.
All colors and ballistic parameters are adjustable via QT style sheets.
There are slight differences in colors for each of the themes.
When the program first starts up, or rather when a scene collection is
loaded, the frontend API OBS_FRONTEND_EVENT_SCENE_CHANGED event would
not get triggered.
(Note: This commit also modifies UI and test)
This makes it so that main preview panes are rendered with the main
output texture rather than re-rendering the main view. The view will
render all objects again, whereas the output texture will be a single
texture render of the same exact thing.
Also fixes some abnormal artifacting when scaling the main preview pane.
