I did see a problem like this once, on an NT machine with
two screens, where it looked like OpenGL just stretched
everything twice as wide to fill the two screens.  But
DisplayImplJ2D doesn't use OpenGL.

However, if each pixel is non-square, the the root of the
problem at some low level below VisAD.  Perhaps someone on
the list knows about such things.

Good luck,
Bill
