"Ratio" Terminology instead of "Time"

[maridany1999]

Currently, the method GetPointAtTime (and similar) uses "time" on its name and comments, which could lead to confusion, especially in contexts where time is not the primary factor. To improve clarity, perhaps, renaming the method to GetPointAtRatio, reflecting its usage of a ratio (where 0 is always the minimum and 1 the maximum) instead of time.
