DNU
http://code.google.com/p/pharo/issues/detail?id=3225

In class Form there are various #fadeImageXXX methods
each with an example in the comment.

Most of them do not work, for example:

Display fadeImageCoarse: (Form fromDisplay: (40@40 extent: 300@300))  
reverse at: 40@40

crashes with a DNU. MessageNotUnderstood: receiver of "bitShift:" is nil

Same problem in Squeak btw.

it 's a closure problem in previous version one block execute several time  
keep some var value. It 's not the case now. we should change :

fadeImage: otherImage at: topLeft
        indexAndMaskDo: indexAndMaskBlock

and update:
fadeImageCoarse: otherImage at: topLeft
fadeImageFine: otherImage at: topLeft
fadeImageHor: otherImage at: topLeft
fadeImageHorFine: otherImage at: topLeft
fadeImageSquares: otherImage at: topLeft
fadeImageVert: otherImage at: topLeft
