Hi,

Attached is an osgtesselationshaders.cpp but designed for quads, which I think 
a lot of people would appreciate since often when doing terrain or ocean 
(certainly when coming from legacy code) you'll most likely be using quads 
rather than triangles.

I found some of the material online (especially the material the 
osgtesselationshaders.cpp was based on) was very unhelpful when it came to 
quads. So this is practically the same code, but modified to use quads instead 
of triangles, so that people have a good starting point for quad tesselation 
for a terrain / ocean setting.

It is a drop-in replacement for 
examples/osgtesselationshaders/osgtesselationshaders.cpp in openscenegraph 
3.2.1 . It will draw an 8x8 quad grid in a single geometry, of the type that a 
heightmap could be easily applied to.

I add no license further to what was already there, in case that needed to be 
said.

Regards,
Chris
