[postgis-devel] Prepared Geometry API

[Obe, Regina]

Ah okay if its 1% then no biggie.  Thought it was worse than that
if as someone said real use case doesn't use L2Cache and Marks' comment about hand optimizing assembly (do all platforms have hand-optimized glibc? I don't even know what that is).  

I probably missed something
in my faulty C garble to Regina simpleton english.  As you were then.

I'm guessing I'll lose 1%. So I'm not crying over it too much. Using
Datum would be nice, but I need a Wizard to tell me it's safe, I'm not
capable of proving it to myself to my own satisfaction.
