Reminder: when making changes to Core2 check all styles please

[ninetydegrees]

If you make any change to Core2 --frontend but also backend, please check whether this also affects any of our official styles and open a bug for them if you don't want to update them as part of your own bug. It's the only way to make sure everything stays up-to-date and functional, and only requires a simple 'grep -ril'. :)
