Gnumeric zoom is not accurate

Hi,

Using Gnumeric 0.6, I've noticed that graphics (eg lines, circles)
do not display correctly when the zoom is changed.  For example,
open the hypothetical sales example spreadsheet and set the zoom
to 75%.  The line and circle have now moved relative to the cells
they should line up with.
