kd-tree building - check all axes for best split, add additional shape-bbox check
extent Container bounds by Eps to fix invisible triangles on borders
new Camera constructor with more intuitive lookat/up vectors
fix camera axes (mirrored images)
better camera angle-of-view
change capitalization of addShape and addLight
