  44 This class represents a dialog that shows a short message and a progress bar.
  45 Optionally, it can display an ABORT button
  46
  47 This dialog indicates the progress of some event that takes a while to accomplish,
  48 usually, such as file copy progress, download progress, and so on. The display
  49 is <b>completely</b> under control of the program; you must update the dialog from
  50 within the program creating it.
  51
  52 When the dialog closes, you must check to see if the user aborted the process or
  53 not, and act accordingly -- that is, if the PD_CAN_ABORT style flag is set.
  54 If not then you may progress blissfully onward.
