The effect when plonking the other waves back in, though, is encouraging. It's not PERFECT, but the fact that lerping the directions of the waves alone seems to work without going completely corrupted means my idea of integrating Flow Mapping into Gerstner MIGHT ACTUALLY WORK.

It still REALLY dislikes it when I try to interpolate wavelengths. Seems that adjusting the wavelength at all causes the wave phase to go absolutely ballistic, causing this whackadoo corruption in the transition zone.

The previous version's normal calculation was to just resample the Gerstner waves at points around the target vertex to find the slope between vertices. It was slow as hell, but dead-simple. This one has been DESTROYING my brain because Partial Derivatives in Pseudo-Tangent Space go BRRR.

A note on the physical coloring part: The previous version just lerped from Cyan to Deep Blue as the water got deeper. This time, I'm playing with Beer-Lambert based math (more math! D:) to simulate the water color directly rather than trying to manually tune things. It's not perfect, but it's neat!
