We use this flag to tell when to assume decoded data is free
from artifacts after a seek. The mpeg1/2 decoder will generate
a dummy frame if decoding is started on a non keyframe. This
will sadly be output from decoder to player and displayed
as a gray screen.

The filter was integrated natively into libavfilter as a source with
name rgbtestsrc.

The licence was changed from GPL to LGPL with explicit approval from
the original author.

See thread:
Subject: [FFmpeg-devel] [PATCH] lavfi: add rgbtestsrc source,
        ported from MPlayer libmpcodecs
Date: Mon, 11 Jul 2011 16:32:41 +0200

In particular creates a special test_init function, which calls a
common init, and introduces a fill_picture_fn which points to the
filling function.

This is required by the pending patch for adding the rgbtestsrc
source.

It is natively included in libavfilter.

Fixes a crash when forcing libc to strictly adhere to malloc sizes.

Prevents overflows on very bright scenes when adding dither,
which may lead to black dots.

The file name is redundant and brittle across file renamings.

Without it, Doxygen cannot separate them into different sections.

This doesn't access avcodec_opts, so it works with the new options
passing system.

Makes opt_bitrate() unneeded, so it's removed.

This fixes a bunch of related warnings where Doxygen assumed that the
documentation belonged to the macro and not the function.

This fixes a bunch of unused function warnings.

Mainly ported from 8-bit H.264 predict.

Some code ported from x264. LGPL ok by author.
