pair origin ; origin = (0,0) ;
is used in many places in the MP macros, and redefining this "constant"
would cause all sorts of problems, as Hans indicates.

I do this a lot, but recognize that it only makes a difference with
respect to subsequent drawing actions: The MP graphic, when "sent back"
to ConTeXt is treated as a box (defined by its bounding box) and placed
by ConTeXt according to its context (no pun intended)!
One could always play with this bounding box for interesting effects:
setbounds currentpicture to ((bbox currentpicture) shifted (xx,yy)) ;
for example.
