test case

I'll upload a test case.  Notice that when selecting text in the test case, the selection gets off.

I think this is a bug with SVG fonts, but I'm not sure.

This appears to only occur with the combination of complex text, SVG fonts, and the CSS property text-rendering: optimizelegibility. CC'ing our font expert.

Yes, on Chromium Linux we crash, but I think if we fix this, it will also fix the crash.

DRT Test Case (also crashes in browser)

Hitting the real issue in debug builds requires removing a ASSERT_NOT_REACHED that should not be present at line 209 of SimpleFontData.h.

Safari, Chrome, and Firefox all agree on rendering for this test case. I don't believe there is any remaining compatibility issue.
