C985 red text jaggies fix

[codex]

I played with avisynth filters today and came to this:

Video resolution is 1280x720
First line is from original video and second one is after applying the fix.
That was done with FixBrokenChromaUpsampling() of avisynth.

So I asked on IRC if its possible to implement it in OBS somehow and got assured (by muf) that it shouldn't be too difficult to implement.
I know Jim also have this capture card so I hope it will be interesting to him also :)

To clarify: http://avisynth.org/mediawiki/FixBrokenChromaUpsampling

Basically, some capture devices treat progressive 4:2:0 video as interlaced, resulting in wrong ordering of picture lines when upsampling to 4:2:2. When doing 4:2:2 to 4:4:4 conversion in OBS (I believe this is done in a shader?) simply swapping out the order of the lines should be trivial.
