The introduction of reading _SARNum/Den values spurred
the idea of making sure that users can turn the frameprop
value reading ability on and off.

Resizing is a much more common activity in AviSynth scripts
than the kind of broad color work that would potentially
severely impact the usage of the color-related frameprops.
Since the source filter sets the SAR values, but then it
would be quite possible for a user to manipulate the resolution
without updating the prop values for _SARNum and _SARDen, it
would become extremely easy to get it wrong.

So reading _SARNum/_SARDen is *possible*, but requires
user opt-in with the -read_frameprop_sar boolean option.
And that then lead to fleshing out the others into their
own options, and a mass frameprop on/off setting.

Stephen Hutchinson (9):
  avformat/avisynth: read _SARNum/_SARDen from frame properties
  avformat/avisynth: add read_frameprop_sar option
  avformat/avisynth: add read_frameprops option
  avformat/avisynth: add read_frameprop_field_order option
  avformat/avisynth: add read_frameprop_range option
  avformat/avisynth: add read_frameprop_primaries option
  avformat/avisynth: add read_frameprop_transfer option
  avformat/avisynth: add read_frameprop_matrix option
  avformat/avisynth: add read_frameprop_chroma_location option
