Allow specifying multiple animation versions, for different resolutions, when setting the animation to use via wxAnimationBundle class which is a much simpler version of wxBitmapBundle used elsewhere. This is not implemented for the native GTK version yet. Update the sample, even though the difference in it is not really noticeable as the "high DPI" throbber is just a scaled up version of the existing standard DPI animation produced using gifsicle.
