<description>
Finds the key index by time in a given track. Optionally, only find it if the approx/exact time is given.
If [param limit] is [code]true[/code], it does not return keys outside the animation range.
If [param backward] is [code]true[/code], the direction is reversed in methods that rely on one directional processing.
For example, in case [param find_mode] is [constant FIND_MODE_NEAREST], if there is no key in the current position just after seeked, the first key found is retrieved by searching before the position, but if [param backward] is [code]true[/code], the first key found is retrieved after the position.

<description>
Returns the interpolated value at the given time (in seconds). The [param track_idx] must be the index of a value track.
A [param backward] mainly affects the direction of key retrieval of the track with [constant UPDATE_DISCRETE] converted by [constant AnimationMixer.ANIMATION_CALLBACK_MODE_DISCRETE_FORCE_CONTINUOUS] to match the result with [method track_find_key].
