Comment 20 for bug 725434

So I've been working for a bit on trying to make libcairo built with gl co-installable with the standard libcairo in a way that would allow tweaking the ld paths to use the gl version but hit quite some issues on the way.

I'm attaching a debdiff of the tweaked version with some comments of the limitations of the approch, if someone wants to pick up feel free, to me it seems to start being hackish and work over what is reasonable to spend to just support wayland in universe for natty.
