by adding a ComputeTransformCallback to osg::Transform, and have now removed the recently added AutoTransform since it is nolonger required. Have also updated CullVisitor to account for the new ways for tracking transformation matrices in the scene.

|
* (eg see GeoSet.cpp). There are 20 types of drawable counted - actually only

* 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.
