# ::tk_dialog:
#
# This procedure displays a dialog box, waits for a button in the dialog
# to be invoked, then returns the index of the selected button. If the
# dialog somehow gets destroyed, -1 is returned.
#
# Arguments:
# w - Window to use for dialog top-level.
# title - Title to display in dialog's decorative frame.
# text - Message to display in dialog.
# bitmap - Bitmap to display in dialog (empty string means none).
# default - Index of button that is to display the default ring
# (-1 means none).
# args - One or more strings to display in buttons across the
# bottom of the dialog box.
