is_point1d

<code>is_point1d()</code> tests whether an object has a "Point1D" class

Dilate, permute, project, reflect, rotate, shear, and translate 2D and 3D points.  Supports parallel projections including oblique projections such as the cabinet projection as well as axonometric projections such as the isometric projection.  Use 'grid's "affine transformation" feature to render illustrated flat surfaces.
