Hi Vittorio

Yes, you are correct

The path and the end result are 2 different things
The end result that this funding is for is a clean libswscale
aka a clean "image convertion lib inside FFmpeg".

I think the path should be decided by the developer doing the work, if she wants to
extend libplacebo and import that, sure ok too with me

Only the contents of the C, H and asm files affects the people using the code
And i expeted some reused code, so i call it cleanup.

Things called "rewrites" also often failed. So its IMHO a sligtly cursed term,
but they are just terms, what the rsult is matters

thx
