- Tue, 21:06: A little known fact http://j.mp/hu2afi
- Wed, 00:04: Adding John Hobby's "tension" formula to the OCaml. Makes things a lot more terse. Probably later the direction-finding formula, too.
- Wed, 02:42: Because OCaml has IEEE floating point, when specifying tension I can use literally "infinity", and so get a true two-point bezier curve. :D
- Wed, 03:10: In PS fonts most on-curve points should be at local x and y extrema, thus Hobby's direction guesser is less important. But still useful.
