It is not possible (AFAICT) to make a *unified* design that works for 
multiple-buffer and single-buffer city description drawing.  But it is 
possible to make a design that works for single-buffer city description 
drawing only.  And it's also possible to implement single-buffer drawing 
for all GUIs.

So, why can't the FS client draw the city descriptions to the backing store?
