Helper template to handle XIntegerBitmap method forwarding to BitmapCanvasHelper.
Helper class for basic canvasbitmap functionality.
css::uno::Reference< css::rendering::XGraphicDevice > mxDevice
MUST hold here, too, since CanvasHelper only contains a raw pointer (without refcounting)

Not threadsafe! Returned object is shared!

CanvasBitmap(const BitmapEx &rBitmap, css::rendering::XGraphicDevice &rDevice, const OutDevProviderSharedPtr &rOutDevProvider)
Must be called with locked Solar mutex.
