04070dbca0 libx265: Fix 'braces around scalar initializer' warning 
x265 Reordered the x265_picture fields in the commit

51b1518de2 (diff-945b5354d8767dfac13334f2d22cf58fR107)

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

7b734ee55d lavf: Open PICT images with Quickdraw 
Update the pictor test to use the pictor codec, as both formats share
the .pic file extension.

34efb8a169 quickdraw: Support direct pixel blocks 
Data is stored in separated components so rework decode_rle() to support

bb2cb0a66d quickdraw: Switch to greedy parsing 
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.

9e66b39aa8 diracdec: avoid overflow of bytes*8 in decode_lowdelay 
If bytes is large enough, bytes*8 can overflow and become negative.

In that case 'bufsize -= bytes*8' causes bufsize to increase instead of
decrease.

This leads to a segmentation fault.

110f7f35fb aacpsy: correct calculation of minath in psy_3gpp_init 
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).

If max in clean_index is set to a negative ast->sample_size, the
following loop never ends:

            max += max;

Thus set ast->sample_size to 0 if it would otherwise be negative.
