Thorsten Behrens 09b546cf9c Fix overloaded-virtual warning in canvas
With enabled -Woverloaded-virtual gcc warning (see
http://lists.freedesktop.org/archives/libreoffice/2011-March/009567.html),
canvas exposed a nasty clash between WeakComponentImplHelper::disposing
and XEventListener::disposing. Fixed by overriding *once* in baseclass,
and then calling disambiguated, renamed methods.

/** Mixin Sprite
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 WeakComponentImplHelperN
template args, and furthermore, don't want to derive
::canvas::CanvasCustomSpriteBase directly from
::canvas::Sprite (because derivees of
::canvas::CanvasCustomSpriteBase have to explicitely 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.
