enterSandbox		Enter sandbox mode (one-way; there is no way back)
mountAppData	mountName="usr", folderName	Mount a folder of this application's own data as /usr or /usr2
unmount	mountName="usr"	Unmount /usr or /usr2
droppedFiles		Files the user has dropped on the window: [{name, isDirectory}]
dropPosition		Where in the window the last drop landed: {x, y}
mountDropped	index=0, mountName="usr"	Mount one of those dropped files as /usr or /usr2
clearDroppedFiles		Forget the dropped files (the next drop clears them anyway)

Once enterSandbox has been called, paths are virtual: they are always /-separated, name one of the mounted disks, and reach nothing else. Before that, they are ordinary host paths.
