A more extensive test shows that isAllWhite now works only for depth +/- 32, +/-1 or for widths that are multiples of 16.

FormTest-testI...iteEvenMore.st is a method that does a more comprehensive test on various widths.

all filled black forms pass the test but the filled white forms do not.

Yours in curiosity and service, --Jerome Peace.

I'm closing this issue as the original fix and tests were harvested as update 7134 and released in Squeak 3.10.

I've created a new issue 0007231 with wiz's more extensive test and report.
