/*
Summary:
WaveWarpModifier allows nonlinear reshaping of a waveform by warping it horizontally (time-axis) and vertically (amplitude-axis). Users can set warp powers and choose asymmetric transformations, creating a wide range of waveform distortions. Interpolation between keyframes and these nonlinear transformations can produce evolving, dynamic waves that move beyond simple linear scaling.
