From Michael McDonnel, "The tessellation shader example has a small bug.The middle of the
...
geometry is clipped as soon as it is tessellated. The clipping is
probably caused by rounding errors because it is only in one spot. The
clipping disappears when the camera is moved, and reappears when it is
moved back. Expanding the the bounding box fixed the clipping bug."
Tweaked by Robert Osfield to expand it to a -1 to 1 unit box.
Actual clipping bug is not due to rounding errors but the shaders creating vertices outside the bounding box of the original input vertices

Introduced new shader composition approach that utilizes #pragma requires(), #pragma import_defines() and #ifdef in GLSL to enable multiple different versions of shaders based
...
on defines passed in from osg::StateSet::setDefine(..).
