drag_region2drag_region2DragRegion2drag_region2DragRegion2DragRegion2 — Interactive movement of a region with fixpoint specification.
You use drag_region2drag_region2DragRegion2drag_region2DragRegion2DragRegion2 to move a region on the display by mouse.
It corresponds to the operator drag_region1drag_region1DragRegion1drag_region1DragRegion1DragRegion1 with the
difference, that the position of the mouse cursor can be determined.
Gray values of the regions are not moved.
With moving the input region it is not sure whether the gray values of the
output regions are filled reasonable. This may occur if the gray values of the
input regions do not comprise the whole image.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).

drag_region2drag_region2DragRegion2drag_region2DragRegion2DragRegion2 returns 2 (H_MSG_TRUE), if a region is entered, the window
is valid and the needed drawing mode (see set_insertset_insertSetInsertset_insertSetInsertSetInsert)
is available.
If necessary, an exception is raised.
You may determine the behavior after an empty input with
set_system(::'no_object_result',<Result>:)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>).
