[WF-General] A little help

Well, in our initial implementation we'll just use a regular mesh, but 
in the future we need to use a more special rendering type, since ocean 
render presents some extra issues. Any such implementation would need to 
read the top of the ocean to decide where to place the sea level.
(We currently have support in Ember for Hydrax water 
(http://www.ogre3d.org/wiki/index.php/Hydrax) but it's currently 
disabled since it's too resource hungry.)

So, no, it wouldn't present any issue either for our initial 
render-using-mesh hack and future 
render-using-specialized-render-object. It would be pretty cool.

The ocean entity could also contain some information about the current 
wave height etc., so it would be possible to simulate different kind of 
weather. This should be some kind of value general enough that the 
client would then be able to use that in conjunture with the different 
depths of the waters to present different sized waves depending on the 
depth. We could also add information of the waters colour etc. These are 
all thoughts for the future however and not something we want to 
implement right away.
