LayoutTest for SVG pattern crash

This patch includes a test case for the bug.

Luckily I was wrong and the previous patch did not break the mentioned test
(stroked-pattern.svg) or the one of batik.

This crash is still a general issue and happens if the pattern size is smaller
than the tile of the pattern and the attribute overview is set to visible. Also
the pattern size must be smaller than 0.5 in any dimension.

I would suggest to review "Proposed fix for a Chromium SVG crash" again with
this patch as Layouttest.
