I don't understand the last sentence (perhaps I don't understand
Yahvuu's proposition correctly). If color values are never changed,
the only place that erasures would result in an "image background
color" (being revealed) is on the bottommost layer. Is that what is
If so, then I would consider the lack of consistency in the tool's
behavior across layers to be a problem.
If it is not so, what determines whether or not erasure results in the
RGB part of the "image background color" being blended with the layer
