%description
In order to smoothly animate the transformation of polygons and paths,
many aspects needs to be taken into account, such as differing number of
control points, changing center of rotation, etc. The 'transformr' package
provides an extensive framework for manipulating the shapes of polygons
and paths and can be seen as the spatial brother to the 'tweenr' package.
