Trends in Mozilla’s central codebase

As part of my recent duties I’ve been looking at trends in Mozilla’s monolithic source code repository mozilla-central. As we’re investigating growth patterns and scalability I thought it would be useful to get metrics about the size of the repositories over time, and in what ways it changes. It should be noted that the sizes are for all of mozilla-central, which is Firefox and several other Mozilla products. I chose Firefox versions as they are useful historical points.
