A HiRes double buffer or normal resolution?  When HiRes assist is turned on,
there is no longer a one-to-one (or N-to-one) correspondence between the actual
display buffer and any normal resolution double buffer.  But with 
HiRes assist turned
off, there is an exact four-small-pixels-to-one-big-pixel correspondence.

Here's a related question.  I've written code to allow me to drag bitmaps
around over a background using double buffering.  This works perfectly,
except on a Clie.  On the Clie, when I drag a bitmap over text (presumably
HiRes), pixels in the text get erased, little by little, with each
successive drag over the text.  Pixels that aren't part of text are not
affected.  If I turn HiRes assist off for this app, the problem goes away.
