Here is a example I just did in FishEyeMorph that worked
"Round to a number divisible by grid. Note that the superclass has
its own implementation."
| g gridSize |
gridSize _ self gridSizeFor: aPoint.
Transcript show: aPoint asString.
g _ (aPoint - (2 * borderWidth)) // gridSize.
srcExtent _ g * gridSize.
gridNum _ g.
^super extent: self defaultExtent
