The irksome thing is that there IS no "long orientation":  the package
is square, with pads 1, 2, and 3 along one side, 5, 6, and 7 along
the opposite side, and 4 and 8 opposite each other on the other two
edges.

What's more, in the datasheet, the chip is usually pictured from
the underside, with pin 8 being at the "top" of the diagram, and
numbering clockwise from there with 1 at the upper right.

That diagram MIGHT lead one to believe that the X-axis would go
"left-right" (as I speculated in the OP), with the Y-axis orthogonal.
One would be wrong. ;-)  The actual orientation is the other way:
Y goes "left-right" and X "up-down".  Grrr.
