## Description

GstInterpolationControlSource is a GstControlSource, that interpolates values between user-given control points. It supports several interpolation modes and property types.

To use GstInterpolationControlSource get a new instance by calling `gst_interpolation_control_source_new()`, bind it to a GParamSpec and set some control points by calling `gst_timed_value_control_source_set()`.

All functions are MT-safe.
