Modify water animation based on surface area.
Also, side and bottom animation pieces as well.
The water will propagate in later mythruna versions, not much use for side and bottom really 
How do you want the animation to be changed? Lower waves with less area or what? I don think the work implementing this is in any way justified by the resulting looks…
Yeah, I would have less amplitude on smaller bodies of water, and lower frequency on larger bodies of water.
The real problem is detecting this and having it all match up. When water propagates more naturally, I will need to deal with a whole bunch of new issues… hopefully varying the waves is something that falls out of that naturally. Otherwise, rivers will look very strange.
