dependency resolution and management. Things are currently in a state of transition, but the important patterns have been established and I'll aim to sweep through all of Narya, Nenya and Vilya in the near future and do everything properly. Going through the other million-odd lines of code we have scattered across our various projects that use these libraries is not something I plan to do, so we'll be maintaining backward compatibility with the old static member method, though I hope to strive toward eradication of that usage entirely in MSOY while we still have a fighting chance. Given that some of our projects will continue to use the static member method in perpetuity, I'm not going to @Deprecate those fields because that would fill their logs with so much spam that they'd have to turn off deprecation warnings which would make life worse for them. So instead we'll settle for the big scary comment warning people away from the old bits. git-svn-id: svn+ssh://src.earth.threerings.net/narya/trunk@5153 542714f4-19e9-0310-aa3c-eee0fc999fb1
