before you leave, jon, maybe you can
answer a couple of questions for me...

you once coded a little demo that had
a page-scan that scrolled line-by-line
in a window, according to the position
of the cursor in an adjacent textarea...

my questions are concerning that code.

specifically, was it python or javascript?

i think you made the code open-source.
if that's correct, where can it be found?

and, maybe the most important of all:
how was it, exactly, that you did that?

the synchronization part's easy enough,
but how did you get the coordinates of
each line?  did you do that on-the-fly?
can you get them for an arbitrary scan?

i do this in my offline (realbasic) apps
by assessing the color of the pixels at
several specific points in the scan, but
i don't see how to do that in a browser.

so is _that_ what you were doing there?

and finally, if that is indeed what you do,
can you do such pixel-color-probing on
any old div (or screen location), or will it
only work on graphics, like page-scans?
