A Virtualizer can help to save memory by storing data on disk instead of
using the VM memory. If you want to use this feature, make sure that the app
can access the disk and that enough space is available. Then assign an
instance of this class to the TextureManager or an Object3D. For textures,
call TextureManager.virtualize(Texture) on those textures that should be
swapped to disk.
Creating a new instance of this will clean all previously stored data from
disk. If you want to reuse the affected data anyway, you'll run into
It's mandatory to set the current context by calling setContext(Context)
before assigning it to anything.
