Animated Icon

Shows how to animate an icon inside a plain Win32 dialog. The key move is loading the .ani as a cursor (LoadCursor with IMAGE_ICON semantics) and handing it to a static control via STM_SETIMAGE - Windows then plays the animation frames automatically. The commented variants show the same for an AniIcon resource and for loading straight from a file with LoadImage. Use it when you want a live animated badge in a dialog without any timer code.
