Begins a drag operation on left mouse button press by capturing the mouse and recording the initial cursor and thumb positions used later to compute drag offsets.
Clears the pressed visual state when the mouse leaves the thumb, unless a drag operation is currently in progress (mouse captured).
Updates the thumb's position while it is being dragged (mouse captured), or while the left
button is held down over the thumb without capture (used inside the non-client area of RadForm).
Ends the drag operation started by OnMouseDown(MouseEventArgs), releasing mouse capture and applying the final thumb position.
Provides a routine to paint element's content when system skin appearance is desired.
