Oh, that's probably complicated. I'd say that when debugging, variable tooltip
is the element that most surely needs to be shown, so I'd rather suppress
code nagivation tooltip first, and then see if somebody comes up with a clever
scheme to show both.

Well, ActiveTooltip is a fully reusable class, that should not care about debuggers
or language support. I guess I have two more specific questions:

  - It's OK to suppress language support tooltip when debugger is active (no matter
    what perspective is open)? Or it's better to suppress it when we're in debug
    perspective *and* debugger is running? 
  - What is the code in language support that installs the hook that shows the
    tooltop?

If I know this, I'll probably be able to hack something up.
