But would it be really necessary to access these faces each time the 
indicator would be drawn?  We could for example cache the values of these 
two colors somewhere, or decide to do something different and use a 
specific function to set these two colors without going through the whole 
face machinery, something like (set-busy-indicator-colors FOREGROUND 
BACKGROUND).
