straight lines. In other words, if you take a number of points that fall on a straight line and

apply an affine transformation to their coordinates, the transformed coordinates will describe a

straight line in the new coordinate system. General affine transformations include all the sorts

of transformations that CLIM uses, namely, translations, scaling, rotations, and reflections.

The protocol class of all transformations. There are one or more subclasses of

these classes is explicitly unspecified. If you want to create a new class that behaves like a

transformation, it should be a subclass of

All of the instantiable transformation classes provided by CLIM are immutable.

Returns

An instance of a transformation that is guaranteed to be an identity transformation, that is, the

transformation that "does nothing".
