<BLOCKQUOTE>
Statistics base class. Used to extract primitive information from
the renderBin(s). Add a case of getStats(osgUtil::Statistics *stat)
for any new drawable (or drawable derived class) that you generate
(eg see Geometry.cpp). There are 20 types of drawable counted - actually only
14 cases can occur in reality. these represent sets of GL_POINTS, GL_LINES
GL_LINESTRIPS, LOOPS, TRIANGLES, TRI-fans, tristrips, quads, quadstrips etc
The number of triangles rendered is inferred:
each triangle = 1 triangle (number of vertices/3)
each quad = 2 triangles (nverts/2)
each trifan or tristrip = (length-2) triangles and so on.</BLOCKQUOTE>
