Yes.
Getting the horizontal location right, as you'd
have to in order to do
precise
drawing, might be a bit more complicated, don't
you think? an 8-pixel
extent of
uncertainty is quite a bit on a 640-pixel display.
But it's usually less than 8 bits. For example, the pen I built (which had
assorted other problems as per my other responses) was mostly used on a
4-bit-per-pixel display (16 colours) or a 2bpp (4 colour) display, so the
resolution was usually 2 pixels or, at worst, 4.
