Yes, I do. I initialise my features on max locations, then run detection 
on all cornery regions.

Sounds cool. In my experience the SSE detection has occasionally been a 
bit haphazard in the configure script - it'd be nice to have a way of 
knowing that you are in fact getting the SCREAMING SIMD version if you 
want it. Currently, the compile brekage if you don't accomplishes that.
