This is AnnWinRTRenderingEngine implementation of AnnRenderingEngine.Render. It will render the objects in the Leadtools.Annotations.Core.AnnRenderingEngine.Container to the Context. The container objects might be scaled to fit into the destination rectangle.
This method uses the mapper in Leadtools.Annotations.Core.AnnRenderingEngine.Container to calculate the destination rectangle and any other transform to be applied.
