Runtime configuration system for skia.  This will allow developers to control settings at launch time without relying on compile-time flags or recompilation.  It can be used to turn features on and off, as well as to control numeric quantities to 'tune' algorithms.  Once I make sure it's working across all platforms I'll send out a quick tutorial on its use.
