It seems that functionality-wise, the bidi code is almost as good as it
was before bidi.  But performancewise, I experience some problems.
I recently started to compile without -DENABLE_CHECKING and other such
debugging code (tho still with -O0 and -g) and am seeing cases where
cursor motion is slow.  The problem is most notable in operations such
as C-e or C-n/C-p (tho those tend to be fast enough as long as I'm in
column 0).
Redisplay itself also seems to be noticeable slower at times.

This usually shows up after I open a few different buffers&frames (like
when I have 10 frames or more (each one showing a single file), where
most frames are sized 80x89).

With -DENABLE_CHECKING, -DXASSERTS, and -DFONTSET_DEBUG, the slowdown is
*very* noticeable, to the point of making Emacs sometimes painful
to use.
My machines range from Atom netbooks to core i7, so not "too old to
be relevant".

That is not true of course.  You'd do it just the same as when
you select text with the mouse.
