Note that Taurus 4.0 is Tango-agnostic only for taurus.core, not for taurus.qt.
Many widgets are not yet tango-independent or scheme-agnostic. This is something that still needs to be done (see the "follow on" section of [TEP3]).

Many parts of the code are already marked with TODOs using the tango-centric "tag". I suggest that we also use the same tag in tickets such as this one.
