@brief Two-dimensional transformation implemented using translation, rotation and scaling
Similar to @ref BasicMatrixTransformation2D, but stores translation, rotation
and scaling separately. This makes it more suitable for e.g. animation, where
there are usually separate animation tracks for translation, rotation and
scaling. This separation also imposes some constraints --- for given object,
scaling is always applied first, rotation second and translation last. In
particular, unlike with matrix-based transformation implementation, it's not
possible to rotate a translated object, for example --- one has to apply the
rotation first and then translate using a rotated vector.
