Thanks, Brian. That sounds great.
As a follow-up, I'd also like to build some integration tests that
demonstrate the camera working with various image pipeline features,
such as rectification and Bayer decoding. But, camera1394 does not
(and should not) have a build dependency on image_pipeline.
The obvious solution is a separate camera integration test stack.
Does one already exist?
If so, is it OK to add some camera1394 tests to it?
If not, is it OK to create one? Where in SVN should that go?
