Details

This happens because we accumulate the error that results from rounding scaleX to get dx. i.e. transform(startx) + n*dx != transform(startx + n) The fix to this is not obvious to me right now so we should probably just fuzz the issue away for now.

I think we could fix this with some careful fixed point math.
Severity: normal → S3
