This file shows a variety of joins. In particular, it shows round joins between
some very short strokes, both in stroked and strokepath modes.

The "stroked" version shows up as full round in ghostscript, but as a pie join
in every other renderer we've tried (adobe acrobat 9, CPSI, Jaws etc).

The "stroked path" version appears to always show as a full round, in Acrobat
and Jaws at least.

Ghostscript was changed recently to always use CPSI_mode for strokepaths. This
leaves us free to change the stroke code to use 'pie' shaped rounds and we
should get exactly what we want.
