Eric Anholt 744aa34ca5 Add an additional meaning to the "dirty" flag. Now, if !dirty && !area, the
pixmaps's contents are undefined, so we won't need to upload the
    undefined contents in MoveIn. Use the ExaCheck* for async ops as well,
    so that dirty is always tracked. While the performance impact for my ls
    -lR test was not significant (though the avoiding-upload path was being
    hit), it's likely to be important for the upcoming Get/PutImage
    acceleration from ajax.
