@brief Base transformation for two-dimensional scenes supporting translation

See @ref scenegraph-features-transformation for more information.

By default the translation is stored with the same underlying type as resulting
transformation matrix, but it's possible to store translation in e.g. integral
coordinates while having floating-point transformation matrix.
