  82         Have to mixin the SurfaceProvider before deriving from
  83         ::canvas::CanvasBase, as this template should already
  84         implement some of those interface methods.
  85
  86         The reason why this appears kinda convoluted is the fact that
  87         we cannot specify non-IDL types as WeakComponentImplHelperN
  88         template args, and furthermore, don't want to derive
  89         ::canvas::CanvasBase directly from
  90         SurfaceProvider (because derivees of
  91         ::canvas::CanvasBase have to explicitely forward the
  92         XInterface methods (e.g. via DECLARE_UNO3_AGG_DEFAULTS)
  93         anyway).

 108         the XGraphicDevice interface. This is because there's a
 109         one-to-one relation between them, anyway, since each window
 110         can have exactly one canvas and one associated
 111         XGraphicDevice. And to avoid messing around with circular
 112         references, this is implemented as one single object.
