simplifyOutline

Simplify a outline object by removing vertices bordering short
edges while not encroaching on any of the outline. At present,
this is done by finding concave vertices. It is safe to remove
these, at the expense of increasing the area a bit.

Reconstructs retinae by morphing a flat surface with cuts
(a dissected flat-mount retina) onto a curvilinear surface (the
standard retinal shape). It can estimate the position of a point
on the intact adult retina to within 8 degrees of arc (3.6% of
nasotemporal axis). The coordinates in reconstructed retinae can
be transformed to visuotopic coordinates. For more details see
