'Tis true. The bitmaps are cached whenever they are used. Also, the outline
algorithms are *VERY* fast, so that you shouldn't notice much of a speed
difference anyway. Finally, there is standard QuickDraw overhead (internally
buffering the text before displaying it to the screen, clipping, adding 
stylistic variations, etc.) which should even things out.
