* Wave simulation speed doesn't anymore depend on surface size, but uses relative distances instead. This change will likely change simulation behavior on existing saves, but can be easily tweaked back using the "Wave Speed" parameter. * Added a new wave brush type, "Depth Change". It uses the change of brush intersection between frames, giving a better looking "wake" for moving objects. It also doesn't leave any "dent" to the surface while remaining still.
