DragImages
------------------------------------------------------------------------
Shows how to customize Ole Drag and Drop to use cell images.

The sample uses the StartDrag event to store the cell image in the
drag/drop Data object. It also handles the DragEnter event to allow
dropping images on the grid and the DragDrop event to actually store
the image in the target cell.

The sample sets the grid's DragMode to automatic, in order to get the
standard mouse behavior to start dragging operations. It sets the
DropMode to manual since the dropping is handled by the event handlers.
