Represent a rotation transformation.
RotationTransform[θ]
RotationTransform[θ, p]
RotationTransform[θ, w]
RotationTransform[θ, w, p]
RotationTransform[{u, v}]
RotationTransform[{u, v}, p]
RotationTransform[θ, {u, v}, …]
RotationTransform[x]
→ TransformationFunction[{{Cos[x], -Sin[x], 0}, {Sin[x], Cos[x], 0}, {0, 0, 1}}]
