The first thing to do is a performance measurement to find out which
primitives still pay their way.  Any that don't offer a substantial speedup
should be discarded.  Substantial would be say -33%.  Sista is making
excellent progress and will be here soon enough that code like
MiscprimitivePlugin's primitives will be optimised well.
