[webkit-dev] Tests that fail across different architectures

The GTK+ port runs layout tests on both a x86_64 and i386 operating
system installations. We have a growing list of tests that generate
different expected results between achitectures. These are almost all
SVG tests. Last night tests were added that even have different
results between our debug and release bots.

Here's an example of a failure:

Tests that depend on this amount of precision are very sensitive to
rounding differences between architectures and library versions. I'm
just curious what the approach should be that isn't skipping these
tests. Perhaps a fudge factor in the output?
