*
* NOTES
*
* This code was audited for completeness against the documented features
* of Comctl32.dll version 6.0 on Sep. 18, 2004, by Robert Shearman.
*
* Unless otherwise noted, we believe this code to be complete, as per
* the specification mentioned above.
* If you discover missing features or bugs please note them below.
*
* TODO:
* Implement repetitive button press.
* Adjust arrow size relative to size of button.
* Allow border size changes.
* Styles:
* PGS_DRAGNDROP
* Notifications:
* PGN_HOTITEMCHANGE
* Messages:
* WM_PRINT and/or WM_PRINTCLIENT
*
* TESTING:
* Tested primarily with the controlspy Pager application.
* Susan Farley (susan@codeweavers.com)
*
* 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).
