OH45 shaping

[yakra]

OH45 is out of tolerance just south of US30_E. A point here will do the trick.
Some shapers, such as +x10 and +x41, don't do much shaping at all.
Overall, many opportunities for shaping points to be converted to regular points.

I'll look through the rest of them as part of a long term cleanup project I plan to get started on next year.
