Hi Jon, Is there a new penrose.inc file also? For instance, the thin and
thick macros have 4 parms now, and in my penrose.inc they have only 3.

Oops.  One of those attached files was supposed to be this one, instead of a
duplicate of the other...  It seems odd that the web version lists the files
as different sizes but have identical content.

Well here is the proper Penrose.inc file. Note that a bunch of the old
patterns are gone.  I haven't converted them to the new way of doing things
yet.  (The angles and positions are described a bit differently now.)

That's really odd.  The http://news.povray.org/... version of the post
(viewed with Firefox) has the same file twice, but listed with different
sizes.  Viewing the same post with Thunderbird has two different files.  In
any case, I replied to my original post with just the penrose.inc include
file.

BTW, you could just pass in a 0 (or anything else) for the 4th parm.  It is
just passed back out to the tile generating macros.  (You will also need to
make a macro PENROSE_context that takes a bunch of parms, just do the same 0
thing there, or return the last parameter unchanged.) OTOH, if you want to
do something like the second or third images in my p.b.i post of the same
name, you will need to use it a bit differently.

Thanks Jon, Yeah, that is strange. Well, it works fine now with the new
penrose.inc.
