It's not fixed in Squeak.
WarpBlt does not work with alpha 0 > < 1.
Another example is rotating a systemwindow (from the halo menu), its dropshadow will be pure black. (i.e. all non-transparent pixels are rendered with their pure RGB component)
(TransformationMorph is removed in Cuis 2.3, rotate halo button is there, but not working)
