I don't think it was superflous at all. I think it was the basic idea
the whole new subtitle rendering proces was based on.
However for a complete and 'final' solution there is always more to
consider and learn. For instance you were drawing to png, but that was
adding additional dependancies, and was also complicating the work for
blending into a stream..
A filter system was needed, and a lossless and easy to draw chroma
format (YUVA) was used instead allowing for greater flexibility in a
Combined with the picture filter system that is (kind of) in
developement, multiple actions will be possible, like scaling,
overlayíng etc etc.
However the basic idea is still very much based i think on your original
suggestions and code. A common format with a centralized position in the
core. The png route though was just adding a bit too much overhead...
In my experience the first implementation of something is destined to
fail, but also is a path for the future.
