--- Comment #3 from Deif Lou <gin...@gmail.com> ---
Sorry, I hit return accidentally and that got posted. I was saying:

* When "include surrounding regions" is selected it is more tricky:
    * Everything from the contour is selected until transparent is reached.
This selects the portions of the top-right strawberry that touch the contour.
    * That selection is inverted, so we have now all the transparent regions
plus the bottom-left strawberry selected.
    * Here is the tricky part: the surrounding regions should be kept, but also
the regions that touch the  surrounding region should be removed. So what is
happening in the strawberries image is that the transparent areas are not
removed from the selection, but then the areas of the selection that touch the
contour are. So, when we arrive at this step we have 2 independent regions in
the selection: one is the bottom-left strawberry and the transparent area that
surrounds that; and the second are the transparent blobs inside the top-right
strawberry. The first one touches the contour. The second one does not. So,
since the regions that touch the contour are removed, only the the transparent
blobs inside the top-right strawberry remain selected.

As you can see it's kind of difficult to reason about this mode whit "include
surrounding regions" option. I think it should be removed. I also think CSP
does not have that option.
