symbols - inprecise rendering

[John Cole]

Ronald,
  There was an issue with a math library in 4.6-4.8.  If you try that in 4.4
or 4.10, that issue isn't there.  If the bug tracker is up, you should be
able to find more information on it.

  The issue was a problem with the round function, if I remember correctly
and could cause the very problem your seeing.  My examples were with squares
on squares.
