[cairo] Rendering error in cairo-1.5.10 and up

[Franz Schmid]

Hi cairo developers,

sorry to bother you with another cairo bug. I discovered that
in cairo-1.5.10 and up (including 1.6.4) the cairo_set_dash function
causes rendering errors with dashed closed polygons.

Please see http://bugs.scribus.net/view.php?id=6971
for screenshots and comments.

The only workaround for that problem is not to close the polygon,
but that is simply not acceptable.

The last working version of cairo is 1.5.8

Best regards
Franz Schmid
