Re: A89: Buffers vs. direct display
Well, it terms of raw speed, it's faster just ot update the areas of the display
that are changing. The problem is that the display refresh may happen in the
middle of your update, which then looks like it flickers when you change it.
This is a reason for using a seperate buffer.
