[IAEP] some very cool features for a capacitive touchscreen

[James Cameron]

Sorry, did I say 6mm wide?  I was inaccurate.  The objects should be
8mm wide.

It might well work with less, but I'm reading from the design
specifications which describe use of stylus, so it would be better to
use 8mm width.  Or do a whole lot of testing to be sure.

"At least two simultaneous touch points are supported, with additional
simultaneous touches supported in some interface layouts.  The
touchscreen detects fingers or a soft-tipped stylus, as long as the
stylus has a diameter of 8 mm or larger (measured within a mm of the
end.)"
