+
+        Have to mixin the Sprite interface before deriving from
+        ::canvas::CanvasCustomSpriteBase, as this template should
+        already implement some of those interface methods.
+
+        The reason why this appears kinda convoluted is the fact that
+        we cannot specify non-IDL types as WeakComponentImplHelper
+        template args, and furthermore, don't want to derive
+        ::canvas::CanvasCustomSpriteBase directly from
+        ::canvas::Sprite (because derivees of
+        ::canvas::CanvasCustomSpriteBase have to explicitly forward
+        the XInterface methods (e.g. via DECLARE_UNO3_AGG_DEFAULTS)
+        anyway). Basically, ::canvas::CanvasCustomSpriteBase should
+        remain a base class that provides implementation, not to
+        enforce any specific interface on its derivees.
