[Rd] Windows freezes plotting large line plots (PR#7856)

[ripley at stats.ox.ac.uk]

This is already addressed in R-patched: we do ask you to check before 
filing a bug report so as not to waste our time.  (It was also discussed 
on R-help: see the archives.)

It is a bug *in Windows* and not one in R: nothing an application can do 
should be that fatal (and this is a perfectly legitimate Windows GDI 
call).  I trust that you will file a bug report in the correct place.

>From the CHANGES file:

   The support for mitred lines encountered a Windows problem with a
   dramatic slowdown if more than 1000 or so segments were plotted in a
   polyline.  We now plot in bunches of 1000, which is less accurate but
   works around the Windows problem.
