>+        [GStreamer] Inconsistent volume scaling
>+        https://bugs.webkit.org/show_bug.cgi?id=197358
>+
>+        Reviewed by NOBODY (OOPS!).
>+
>+        We were inconsistently using cubic volume scaling, which was
>+        casuing inappropriate volume changes at non-deterministic times.
>+
>+        Covered by existing volume tests.
>+
>+        * html/HTMLMediaElement.cpp:
>+        (WebCore::HTMLMediaElement::setVolume): Platform volume
>+        configuration methods are not used for anything, which extends to
>+        the m_volumeInitialized member.
>+        * html/HTMLMediaElement.h: Ditto.
>+        * platform/graphics/MediaPlayer.h: Ditto
>+        (WebCore::MediaPlayerClient::mediaPlayerPlay):
>+        * platform/graphics/gstreamer/MediaPlayerPrivateGStreamer.cpp:
>+        (WebCore::MediaPlayerPrivateGStreamer::paused const): Change the
>+        paused status logging to LOG level, since it's very spammy.
>+        * platform/graphics/gstreamer/MediaPlayerPrivateGStreamerBase.cpp:
>+        (WebCore::MediaPlayerPrivateGStreamerBase::setVolume): Switch to
>+        linear scaling. PulseAudio already applies cubic scaling on
>+        software volumes.
>+        (WebCore::MediaPlayerPrivateGStreamerBase::volume const): Ditto.
>+        (WebCore::MediaPlayerPrivateGStreamerBase::notifyPlayerOfVolumeChange): Ditto.
>+        (WebCore::MediaPlayerPrivateGStreamerBase::setStreamVolumeElement):
>+        Ditto, and also be consistent about using the right scaling
>+        function. This also removes more of the platform volume
>+        configuration as above.
