  Stacked Widget: some fixes and cleanup to select_layer

First off, this reverts the change from a9ba9a9fea. A detailed explanation has been added to the class
member documentation.

Secondly, this removes calls to set_visible. The generator should handle this internally. It seems the previous
code rendered manual calls necessary. This is no longer the case.

Lastly, this fixes an issue where selecting all layers (-1) did not always result in the top-most layer receiving
events. It appears by some quirk of the generator system, only the last "selected" layer receives events, even
if multiple are visible, *not* simply the top-most one in the stack.
