[cairo] [PATCH] Reset dashing for new subpaths.

[Jeff Muizelaar]

Fixes the bug mentioned in b87726ee2aa0220b66ee4d97513c0ac89ffc4621 by reseting
the dash pattern for each new subpath. This is correct behaviour according to
the end of PDF Reference v1.6 section 4.3.2. This patch applies on top of the
zero length dashing patches.
