  64 This class represents a dialog that shows a short message and a progress bar.
  65 Optionally, it can display an ABORT button
  66 <p>
  67 This dialog indicates the progress of some event that takes a while to accomplish,
  68 usually, such as file copy progress, download progress, and so on. The display
  69 is <b>completely</b> under control of the program; you must update the dialog from
  70 within the program creating it.
  71 <p>
  72 When the dialog closes, you must check to see if the user aborted the process or
  73 not, and act accordingly -- that is, if the PD_CAN_ABORT style flag is set.
  74 If not then you may progress blissfully onward.
