* IMPLEMENTATION NOTES:
* This control uses WM_NCPAINT instead of WM_PAINT to paint itself
* as we need to scroll a child window. In order to do this we move
* the child window in the control's client area, using the clipping
* region that is automatically set around the client area. As the
* entire client area now consists of the child window, we must
* allocate space (WM_NCCALCSIZE) for the buttons and draw them as
* a non-client area (WM_NCPAINT).
