    cursor-tracker: Start moving some code to a new file
    
    I want the MetaCursorTracker to mostly be about retrieving cursor
    information. Start moving the code that loads cursor images to a
    new file, MetaCursor. Eventually, MetaCursorTracker's APIs will
    all take MetaCursorReferences, and we can have a clean backend
    split here.
