ellipse_frame_to_shapes

<p>Promote a legacy 5-column ellipse data frame (h, k, a, b, phi) into the
wide <code>$shapes</code> schema. Used by the <code>venn()</code> path, where the precomputed
venn-shape lookup is still expressed as ellipses.</p>

Generate area-proportional Euler diagrams
using numerical optimization. A Euler diagram is a generalization of a Venn
diagram, relaxing the criterion that all interactions need to be
represented. Diagrams may be fit with circles, ellipses, squares, and
rectangles via a wide range of inputs and can be visualized in numerous ways.
