+- review catmull-clark; move vertex points?
+- re-anneal fish
+
+- show constraints (?)
+- show in red if user tries to move a point to an illegal location
+
+- eliminate use of bindinggroupschanged()
+
+- post qfat on my software page
+
+
+With Sequin
+- constraints admit intersections (lattice)
+- constraints may be transformed linearly
