A helper function for interpolating AnimationCurves together. In general, curves can not be directly blended because they will have keypoints at different places. InterpAnimationCurve traverses through the keypoints. If both curves have a keypoint at the same time, they keypoints are trivially lerped together. However if one curve has a keypoint at a time that is missing in the other curve (which is the most common case), InterpAnimationCurve calculates a synthetic keypoint at that time based on value and derivative, and interpolates the resulting keys. Note that this function should only be called by internal rendering code. It creates a small pool of animation curves and reuses them to avoid creating garbage. The number of curves needed is quite small, since curves only need to be used when interpolating multiple volumes together with different curve parameters. The underlying interp function isn't allowed to fail, so in the case where we run out of memory we fall back to returning a single keyframe.
