Override this if you wish to draw the window contents to the backing bitmap
yourself. This can be desirable if you wish to avoid flicker by not having to
redraw the updated window itself just before dragging, which can cause a flicker just
as the drag starts. Instead, paint the drag image's backing bitmap to show the appropriate
graphic {\it minus the objects to be dragged}, and leave the window itself to be updated
by the drag image. This can provide eerily smooth, flicker-free drag behaviour.
The default implementation copies the window contents to the backing bitmap. A new
implementation will normally copy information from another source, such as from its
own backing bitmap if it has one, or directly from internal data structures.
This function is available in wxGenericDragImage only.
