A customer was reporting a problem when they used the function to simulate a drag/drop operation for automated testing purposes. I see the mouse move from one location to another, and the starting and stopping locations are correct on the screen, but the mouse moves instantaneously rather than waiting 500ms between operations.

The usual way of loading an icon from a resource is to use the or function and letting the window manager's icon selection algorithm decide which image to use based on the images available in the icon, the desired icon size, and the current color depth.
