It appears to me that the command to switch from inch to metric, is 
incompletely done.  Or too completely.

Fspeed for instance, is not scaled up to the metric equ, so the sim runs 
painfully slow.  This was observed executing old code probably written in 
2.5.0 days and being used just to exercise the sim.  Back then I could 
apparently set f15, thinking in inches, but in 2.6.0 sim the f15 is being 
done in mm/min.  Painfully slow.

This is a coding error on my part of course, but its going to make me edit 
a boatload of old code should I want to use it again.  It might serve as a 
heads up if it was mentioned in the 2.6 docs.  Or is it?  TBT, I haven't 
checked...

I believe a similar gotcha exists in the MIN_LIMIT/MAX_LIMIT of the .ini 
files. They are not, when given in inches, scaled to match actual distances 
without a trip into gedit for a metric translation.  I got used to the old 
way, and its going to bite me trying to run old code in its inch mode.

Would it not make more sense in the long run to specify this stuff in 
machine units?  That way, we would be forced to do our own math at coding 
time, and the inline math to check this stuff, like the limits I should 
assume, be somewhat simplified and therefore faster at run time.

Just thinking out loud.

Cheers, Gene
