Scale manipulator - attaches to physical shape and draws local axes widgets with box heads.

User can mouse over (turns yellow) and L click/drag to scale along this axis.

void	Draw (const TGLCamera &camera) const override
	Draw scale manipulator - tubes with box heads, in local axes of attached shape, in red(X), green(Y) and blue(Z), with white center sphere.

Bool_t	HandleButton (const Event_t &event, const TGLCamera &camera) override
	Handle mouse button event over manipulator - returns kTRUE if redraw required kFALSE otherwise.
