[pstricks] coordinates of nodes

[John Frampton]

Thanks again Herbert,

I thought I had read every detail in the PSTricks manual.  But I somehow
missed the fact that \SpecialCoor permits recognition of

         (coor1|coor2)

as the point with x-coordinate taken from Point1 and y-coordinate taken
from Point2, and the full power of \SpecialCoor applies to coor1 and
coor2.

(I am writing this out in detail because I suspect that some others may
have missed it as well!)

Our position is that whatever grievances a nation may have,
however objectionable it finds the status quo, aggressive warfare
is an illegal means for settling those grievances or for altering
those conditions. (Supreme Court Justice Robert Jackson, the
American prosecutor at the Nuremberg trials, in his opening
statement to the tribunal)
