    Also, can we be careful not to disturb the user's environment?  I
    noticed, for example, that in the tests for whitebg.m there are
    lines like
    
    set (0, "defaultaxescolor", [1 1 1])
    
    which sets a global preference that may be different from what the
    user has set.  There is no code to save/restore the current settings
    so the user's environment is altered by running the tests.
