#  PURPOSE:  drag&drop send routine for "color" data
#
#  Widgets that are to participate in drag&drop operations for
#  "color" data should be registered as follows:
#
#      drag&drop .win source handler color dd_send_color
#      drag&drop .win target handler color my_color_handler
#
#      proc my_color_handler {} {
#          global DragDrop
#
#          set data $DragDrop(color)
#            .
#            .  do something with $data
#            .
#      }

#   SIDE-EFFECTS
#     Sends data to remote application DragDrop(color), and then
