(The overall inheritance hierarchies of the classes deriving from RepaintTarget
are so over-engineered that it looks easier to make each of those classes derive
from css::uno::XUnoTunnel individually, rather than deriving RepaintTarget from
something like cppu::WeakImplHelper<css::uno::XUnoTunnel>. And see the upcoming
commit introducing that loplugin:unocast on why such dynamic_casts from UNO
types are dangerous.)
