The previous version checked for 14-bit streams and did not properly
work across buffer boundaries.

Use the 64-bit parser state to make extended sync word detection work
across buffer boundary and check the extended sync word for 16-bit LE
and BE core streams to reduce probability of alias sync detection.

with encoder delay.

id should be an integer, not a string. It is also optional, so use
contentType instead which is the proper attribute for these values.

Use 5 frames for video filter tests and a single one for the
pixelformat tests.

Greatly reduces the test duration without reducing coverage.

APIC tags always have a description. Tag writers obviously leave it
empty if there is no description. In this case, libavformat would export
"" as title. Do not set the title instead.

The format uses full range for the gray formats.

x265 Reordered the x265_picture fields in the commit

https://github.com/videolan/x265/commit/51b1518de2414431f36eac592db15b667c25a7b9#diff-945b5354d8767dfac13334f2d22cf58fR107

Now the first field is an integer and not an array.

This stimulates the direct pixel mode in Quickdraw decoder.

Update the pictor test to use the pictor codec, as both formats share
the .pic file extension.

Data is stored in separated components so rework decode_rle() to support
stepping and offsets.

Quickdraw packs data as a series of codes that the application is supposed
to handle, but it does not define any order in which they might appear.
Since it's unfeasible to support *all* opcodes defined by the spec,
only handle well-known blocks containing video data and ignore any unknown
or unsupported ones.

Move palette loading and rle decoding to separate functions to resue them
in other blocks and drop format initialization in init since it can
support more formats than pal8.

Validate width and height.

Add appropriate error messages and reduce r, g, b variables scope.
Drop the now redundant line checks in RLE decoding.

Introduced in e8c4db0d.

This reverts commit 63be97ec.

All those calls were unchecked on purpose, as explained in the comments
in the code.

For max_order = 0 the clipping range is invalid. (amin = 2, amax = 1)

The minimum of the ath(x, ATH_ADD) function depends on ATH_ADD.
This patch uses the first order approximation to determine it.

For ATH_ADD = 4 this results in the value at 3407.06812 (-5.24241638)
not the one at 3410 (-5.24237967).
