15297a8b19 Change offset() to respect $fn/$fs. 
Remove maxstep parameter from offset.
Modify offset_sweep and offset_stroke to no longer use offset_maxstep
or maxstep.
Added a bit of error checking to those two functions so if you pass in
the wrong end treatment it gives a less cryptic type of error
Fixed arc() so it returns 2 points when you request 2 points (instead
of 3)
Fixed teardrop to properly ceil() its segs value.
