Have to mixin the SurfaceProvider before deriving from

implement some of those interface methods.

The reason why this appears kinda convoluted is the fact that

we cannot specify non-IDL types as WeakComponentImplHelperN
|
|
template args, and furthermore, don't want to derive
|
|
::canvas::CanvasBase directly from
|
|
SurfaceProvider (because derivees of
|
|
::canvas::CanvasBase have to explicitly forward the
|
|
XInterface methods (e.g. via DECLARE_UNO3_AGG_DEFAULTS)
|
|
anyway).
