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