Code Review
This pull request introduces the graphene-animation crate, which implements animation primitives like Keyframe, InterpolationBehavior, and AnimationCurve for the Graphene node system. It integrates these curves into the node registry, adds an eval_curve node, and updates the preprocessor to replace AnimationCurve inputs with eval_curve nodes. The feedback highlights two critical issues: first, the preprocessor's node visitor skips preprocessing inputs on nested Network nodes due to an early continue; second, evaluating bezier curves with non-finite handle coordinates can lead to panics or infinite loops, requiring sanitization of the handles.
Important
The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

Maybe we should consolidate both input replace passes into one.
Having one replace_inputs_with_producer_nodes (or similar) that has a match for the node input types for node in the network.
match input {
<resource> ...
<animation_curve> ...
_ => {}

Would you also want to remove the visitor abstractions in this case since there will only be one function that uses it?

This PR adds a
replace_animation_curve_inputsmethod to the preprocessor that replaces anyTaggedValue::AnimationCurve(curve)value inputs in the network neweval_curvenodes. It also refactors out some of the logic inreplace_resource_inputsintovisit_*functions to reduce code duplication.In the future, this will be used in the expose dialog to allow exposing inputs to the timeline.
This PR is a follow-up to #4164. Until that PR is merged, this one will include its commits.
