BitmapDataObject is a specialization of DataObject for bitmap data. It can
be used without change to paste data into the
Clipboard or a DropSource. A
user may wish to derive a new class from this class for providing a bitmap
on-demand in order to minimize memory consumption when offering data in several
formats, such as a bitmap and GIF.

Constructor, optionally passing a bitmap (otherwise use
set_bitmap later).
Returns the bitmap associated with the data object. You may wish to override
this method when offering data on-demand, but this is not required by
Widgets’ internals. Use this method to get data in bitmap form from
the Clipboard.
Sets the bitmap associated with the data object. This method is called when the
data object receives data. Usually there will be no reason to override this
function.
