This adds a COGL_DEBUG=matrices debug option that can be used to trace all matrix manipulation done using the Cogl API. This can be handy when you break something in such a way that a trace is still comparable with a previous working version since you can simply diff a log of the broken version vs the working version to home in on the bug.
