WM_SIZECLIPBOARD
hwnd = HWNDFROMMP(mp1);             /* clipboard-viewer handle    */
prcl = (PRECTL) PVOIDFROMMP(mp2);   /* pointer to RECTL structure */
 
The WM_SIZECLIPBOARD message is sent by the clipboard viewer to the
clipboard owner when the clipboard contains data with the CFI_OWNERDISPLAY
attribute and the clipboard-viewer window has changed size. When the
clipboard viewer is being destroyed or made iconic, this message is sent
with the rectangle size equal to (0,0,0,0), which permits the owner to free
its display resources.
