[Cin] possible patch for x265 on cmake 4.0?

[Andrea paz]

Is there a pacman command to downgrade or an automatic script on AUR.
I put in cmake 3.31.6 and now I should mask cmake 4 so that it will
not be re-updated at next upgrade. But I do the CinGG build and then
go back to cmake 4 with tomorrow's daily upgrade, hoping they will fix
the problem soon.

Compilation went well (with svtav1 and x265); Andrew's patch to remove
clipping to Blur and Title works and, so far, I haven't seen any
problems. Is it possible to remove clipping from Color Space as well?
Histogram Bezier and 3 Color Way we had already tried it without
success.

PS: @Andrew. Did you stay up until 5 a.m. to follow my attempts? I beg
your pardon!
