Description Carl Worth 2005-07-12 05:11:07 UTC

I've got a trivial SVG file, (a single stroked circle), which renders
correctly with the image and xlib backends, but has an errant spike when
rendered with the PDF backend.

I'll attach the SVG file and the current PDF result.

This has the appearance of a very thin, errant trapezoid, and is likely just
a bug in the tessellator.

If the work described in bug #3752 were complete, then this problem would
certainly go away, (since this file would no longer result in trapezoids in 
the PDF output).

Move bugs against "cvs" version to "0.9.3" so we can remove the "cvs" version.

The attachment appears to have been eaten, but the recent implementation of
_cairo_pdf_surface_stroke should most definitely have taken care of this bug.
