They should (up to possible accuracy issues) give the same
result, since the [3][3] element would be used as a divisor with
the same value as the coord scale factors.. But I found that it
was actually carrying out the calculations unless the 1<<16 values
were used, so it was much sloooower.. Until this was fixed in the
server, it was thus best to just use the 1<<16 diagonal factors.
Unfortunately, there also seemed to be a server bug related
to a1-masks that Carsten ran across.

Well done :)
