// Wave Line: If no selection is made, it draws a

// wave line for given length, wave length and wave height

// if selection is made, it uses the selection width and

// prompts for wave length and wave height

// Known issue: Instead of using the actuall bezier function

// I "simulated" it.

// Result: The biger the wave Height, the more off we are

// approx 4px every 100px
