Fixed bug in computation of orthographic projection matrix where it

was not taking into account the Z offset of the near/far planes. Fixed
bug in Camera's unprojection routine where it needed to specify the
negation of the near distance for the initial Z coordinate. Added
getWidth() and getHeight() to Texture2 node. Added convenience method
getPickedPoint() to RayPickAction. Added check to Camera to avoid
recomputing the projection matrix if the aspect ratio was set to the
same value as the last time. Made Group node Iterable.
