…partanJ#189)

Replace the sample table + Newton-Raphson + bisection search, which was
rebuilt on every call, with the closed-form solver of bezier-easing 3.2:
exact, no backward jump on steep curves such as (1, 0, 0, 1), and no
table to build per call.

t outside [0, 1] now saturates to 0 / 1 instead of going through the
old search, which returned arbitrary values there.

Patched version for flatpak and macOS.

Should help fixing flathub build.
