/** Mixin SpriteSurface
Have to mixin the SpriteSurface before deriving from
::canvas::SpriteCanvasBase, 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 WeakComponentImplHelperN
template args, and furthermore, don't want to derive
::canvas::SpriteCanvasBase directly from
::canvas::SpriteSurface (because derivees of
2011-12-01 23:41:42 +02:00
::canvas::SpriteCanvasBase 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.
