QCursor::setDragCursor should be available from the qml equivalent : Drag qml type

QCursor::setDragCursor provides a convenient function to modify the cursor during drag events.

However, its sibling Drag Qml Type does not provide such a method, which makes it impossible to stay consistent across drag and drop events when these are created both from the qml and the cpp.
