Summary0001290: changes to subtitle (burn in) parameters do not seem to trigger re-compression/recreation of content

When doing some burn-in subtitle tests, I noticed that when I adjust Y-offset, then recreate (overwrite) DCP, DCP-o-matic seems to reuse the previous video file, and the burn-in subtitle stays at the previous position in the newly created DCP. I need to delete DCP folder/video folder in order for the new position to take effect. This may also happen for other subtitle settings. Maybe NO changed subtitle settings trigger video recreation, because usually that is not necessary when subs are created as timed-text?

In that case - WHEN burn-in is checked, any change to subtitle settings, appearance, font, etc. should trigger video recompression.

Yup - when I first create a DCP with a black outlined burn-in sub, then change the outline color to cyan, then recreate the DCP, I get the request to overwrite, but the previous MXF from the video folder is reused - the DCP still has the black outline sub. I need to delete the video mxf from the video folder and issue another MakeDCP for the actual settings to be used in a new render.

I could test other parameters as well, but I guess it is safe to assume that in this scenario, no changed subtitle setting at all will trigger a recompression.

Should probably be applied to 2.12.x.

yup - guess it's a 'no-risc' backport.
