-    \class QuadPlane
-    \brief The QuadPlane class holds a 3D model of a large flat plane.
-    When drawing a large flat plane, such as a wall or a floor, it is desirable
-    to decompose it into smaller units to make the shading effects look correct.
-    This class composes a plane out of a configurable number of quads.
-*/
-
-/*!
-    Construct a new QuadPlane with \a size, subdivided \a level times.  By default
-    the plane is 100.0f x 100.0f, and is subdivided 3 times - that is into an
-    8 x 8 grid.
-
-    It is centered on the origin, and lies in the z = 0 plane.
