  14. |                         keyboard       - Drag initiated via keyboard.        |
  15. |                                                                              |
  16. |   DropIndicator     - Enumeration of possible drop indicator values:         |
  17. |                         ok             - Drop permitted.                     |
  18. |                         notOk          - Not permitted at this location.     |

  25. |                                          target to retry its part of the     |

  37. |                                          user is dragging more than 3 items. |
  38. |                                          Performance is increased by not     |
  39. |                                          having to draw an image for every   |

  51. |                                          ignore the images in the IDMItem    |
  52. |                                          objects if they are there.  NOTE:   |
  53. |                                          It is not necessary to create       |
  54. |                                          images if this style is used since  |
