13 *
14 * NOTE: In windows there is a clip and a visible region (just like in PM)
15 * We do not map the Win32 visible region to the PM visible region
16 * as that's rather annoying.
17 * Instead we use the intersection of the win32 visible and win32 clip
18 * region for the PM clip region.
19 * The original Win32 clip region is saved in pHps->hrgnWin32Clip.
20 * The Win32 visible region is saved in pHps->hrgnWinVis.
