Andreas Kling bc3bd28378 LibWeb: Use Newton-Raphson for cubic-bezier easing evaluation ...

Replace the previous caching/binary-search approach with
Newton-Raphson iteration and bisection fallback. This is the
same algorithm used by WebKit, Chromium, and Firefox.

The old code had a broken binary search comparator that could never
return 0 (the second condition was always true when the first was
false), leading to out-of-bounds vector accesses and crashes.

Fixes #3628.
