Bug 380473 disabled antialiased border drawing on Linux due to performance problems doing the PushGroup/PopGroup. We should not ship a final release with this difference in platform parity, so we should either fix the performance problems and reenable it on Linux, or disable it cross-platform.

We need to reevaluate this once my new patch lands for bug 368247 -- I'm pretty sure that there should be no performance difference with or without antialiasing with 1px borders.

I can confirm that Linux border antialiasing no longer shows performance problems. Then again, I caught a build with Cairo 1.4.10, you should get rid of the disabling code when you reland 1.4.10.

I'm sure you don't need my help here. However, bug 368247 has been fixed long ago and I think this one should target beta 1. And maybe it does save you a couple of seconds ;)
