Although I'm a 'nobody' I would probably go for:
----
echo x0,y0:x1,y1:....

Pairs are seperated by ':' whilst values with ','. I guess you could
just use comma's all the way but I personally say that reduces
readability...also means that maybe one day you want to pass only one or
three values...the format could still work.

Easy to parse, a one liner, no fixed length, fits in with the existing
use, etc etc.
