GraphUI: Adopting Vec*f API; Adding Group; Scene + Group are Container, traversing the PMVMatrix throughout childs (-> see TreeTool).

Utilizing the Vec*f (and Matrix4f) API w/ AABBox et al renders our code more clean & safe,
see commit 15e60161787224e85172685f74dc0ac195969b51.

A Group allows to contain multiple Shapes,
hence the PMVMatrix must be traversed accordingly using TreeTool
for all operations (draw, picking, win->obj coordinates, ..).

Hence Scene + Group are now implementing Container
and reuse code via TreeTool and a Shape.Visitor*.

This will allow further simplification of user code.
