## This script adds parallax functionality to any Node2D.
## But be careful, some Node2D descendants may work in a special way
## with the position and global_position properties,
## or have other conflicts with the logic of this script.[br]
##
## [b]How to use[/b]: Add this script to any [Node2D],
## such as [TileMapLayer] or [Sprite2D], or to [Node2D] itself.
## Or move the main sections of the code to your own script.[br]
## After that, this node will have new properties that allow you
## to configure parallax and see it working in the editor just like in the game.[br]

 * \param wavelengths wavelength of each of the 4 waves
 * \param amplitudes amplitudes of each of the 4 waves
 * \param directions direction of each of the 4 waves (each row = one direction). MUST BE NORMALIZED!
 * \param speed global speed multiplier. Individual wave speed depends on Wavelength
 * \param steepness Gerstner wave 'Steepness' parameter. Modulates the horizontal offset of points
