@brief Base for transformations

Provides transformation implementation for @ref Object instances. See
@ref scenegraph-features-transformation for more information.

@section SceneGraph-AbstractTransformation-explicit-specializations Explicit template specializations

The following specializations are explicitly compiled into @ref SceneGraph
library. For other specializations (e.g. using @ref Magnum::Double "Double"
type) you have to use @ref Object.hpp implementation file to avoid linker
errors. See @ref compilation-speedup-hpp for more information.
