            Description

            A client has sent in a architecture PDF that has a very large number of q and Q operators in it and our restore method (Q) is taking up about 50 seconds of time just doing Area equals calculations.

            In the past we have tried to optimize this by using the clip's bounds rather then area. I would like to revisit this and try to figure out why previous approaches have yielded regressions.
