+This is an abstract base class for many of the more
+complex classes in the ssgAux 'collection'. The idea
+is that these are really ssgGroup nodes - but they
+behave in such a way that you are never concerned
+with the nodes they create beneath themselves.

is an optional user-callback that can be used to feed water depth

+values into the simulation. The wave system will likely call this
+function many thousands of times per frame - so make sure your
+depth function is very efficient. If you don't provide a depth
+function then the water will be assumed to be infinitely deep.

You can determine the number of polygons used to render
the patch of waves, the size of the wave patch and the amount

+of texture repetition. The 'EdgeFlatten' setting determines
+to what distance from the edge of the patch the waves are
+gradually flattened out. This is useful because it allows
+you to keep all those expensive wave polygons close to the
+camera - and feather them out over range so that they blend
+gently into a larger flat ocean.
<p>
Designing waves by calling the ssgaWaveSystem API is quite
difficult. You are advised to use the wave designer program
