Consider removing easing of individual Transform properties #13
Description
Currently, we have components like TranslationInterpolation, RotationInterpolation, and ScaleInterpolation. However, this level of granularity is rarely necessary, as you typically want to interpolate either the whole Transform or nothing at all.
It also causes some other weirdness: what if you remove TranslationInterpolation but keep TransformInterpolation? Currently, even removing TransformInterpolation doesn't necessarily work like you'd expect, since the individual interpolation components are kept, and interpolation is not disabled.
We should consider remove the interpolation of individual Transform properties, and just having TransformInterpolation and TransformExtrapolation. This would reduce complexity and weirdness, and could even has less overhead than running many individual interpolation systems. Benchmarking might be useful here.
