We don't do anything with it yet.

It replaces the "fake" demuxer and decoder, and partially
the mjpeg one.
It does not rely on the extensions to detect the format.
The detected picture formats are: XCF, GIF, PNG, TIFF, BMP, PCX,
LBM, PNM, JFIF and SPIFF(Jpeg).
The reload feature of the fake:// demuxer is lost, as well as the deinterlace
feature of the fake decoder, patches are welcome.

It closes #3107 and #3388, and modifies #2295.

That fixes the y4m with unknown chroma that avformat can read

But you need careful, if you compile without X and then run with an X-enabled PulseAudio, boom.

Closes: #3650

 It fixes 'on top' behaviour when going fullscreen (at least for linux), and
it avoid having a 'Untitled Window' in the taskbar when fullscreen.

It properly fixes #3526.

The maximum number of surfaces it will allow is now 128, but the actual value
used is configured by the core (around 20-30 when DR is used, a few otherwise).
