I think your proposal about ":results graphics" is more flexible and
complies the documentation. Since the patch has no real problem and
the feature is useful indeed, I hope it can be merged instead of mine
after the problem of documentation is resolved.

As for other features in the patch, maybe it is better to convert
dict/dataframe/array to table/list only when the result type is
explicitly set to table or list?
