Thanks Rick! I wonder what happens to the
pressure information if the user has a habit
of resting their palm on the screen as they write.
I'm sure it is only sensitive to the pen tip
but the pressure varies as the writer pivots
on the palm. Hmm. Not important...
I suppose to get more details one would have
to dig around the MS announcements or any
papers they've published in the recent past.

It seems to be a vector format storing (sampled) gestures from a pen.
The sampling rate seems to be hardware-dependent. Each sampled
point seems to contain pressure information. Different pen tips
can be stored for faithful rendering/resizing at differing resolutions.
The vectors can have text recognition applied: CJK writing has a very
fixed order, so storing the stroke order and direction (rather than
just a bit map) is important and may allow better recognition than
bad Latin writing could have. But the usual thing would seem to
be storing the graphic and overlaying it on some other image: if the
text recognition fails, you still have the vector format.
