Commit Message

Avoid temporaries when preparing step plots.

The previous implementation of `pts_to_{pre,mid,post}`step was fairly
unefficient: it allocated a large array during validation (`vstack`),
then a second array to build the return tuple, then converted the
columns to a tuple, then immediately converted the tuple back to a new
array at the call site (to construct a Path).  Instead, just create a
single array and work with it all along.

Also some minor related cleanups (moving imports in lines.py, in
particular not exposing the individual `pts_to_*step` functions anymore
(they are not directly used, only via the `STEP_LOOKUP_MAP` mapping).
