- Improve performance of V8 string conversions (issue #323). - Add V8 performance test to cefclient (issue #323). - Add the ability to return exceptions from V8 accessors (issue #327). - Return undefined instead of null from a V8 handler if no return value is specified (issue #329). git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@291 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
