This puts in most of the infrastructure needed to allow us to switch between different densities at run time. The main remaining uses of the global are to initialize the Bitmap object (not sure what to do about that since it doesn't have anything passed in the constructor to get this information from), and being able to load drawables if we need a different density than what was preloaded by zygote.
