Geometry independent reflection

[GoogleCodeExporter]

A suggestion:

The projected reflection is completely independent of the actual water
geometry (waves) - the effects are most noticable when looking in wind
direction (see screenshot - although lighting clearly suggests the wave is
there the reflection looks just like on a plane).

Personally I think...

-tempPos.xy = v.xy + disp * N.xy;
+tempPos.xy = v.xy + disp * - v.z * N.xy;

...in distortGen() looks a lot more realistic (it no longer looks like the
reflection is cutting through the wave-tops).

But as this is probably highly subjective I'll leave it up to the
maintainer. :-)
