           Summary: SetWindowOrgEx not handled correctly in various
                    functions
           Product: ReactOS
           Version: 0.2.9
          Platform: VMWare 4

            Status: NEW
          Severity: normal
          Priority: P3
         Component: Win32

When the display coordinates are displaved with SetWindowOrgEx, various Windows
functions don't behave correctly. The tested functions are DrawText,
ImageList_DrawEx and FillRect. The problem seems to be the clipping rectangle in
all 3 cases.

See the above URL for a sample C project and two images showing the problem.

Sample code:
	GetClientRect(hWnd, &rt);
	GetTextExtentPoint(hdc,szHello,strlen(szHello),&sz);
	GetModuleFileName(hInst,buf,sizeof(buf)-1);
	himl=(HIMAGELIST)SHGetFileInfo(buf,FILE_ATTRIBUTE_ARCHIVE,
		&sfi,sizeof(SHFILEINFO),SHGFI_SYSICONINDEX | SHGFI_LARGEICON |
 		SHGFI_USEFILEATTRIBUTES);
	hbrush=CreateSolidBrush(RGB(128,128,128));
		
	rt.top=0;
	rt.left=0;
	rt.right=sz.cx;
	rt.bottom=sz.cy;

	rt2.top=100;
	rt2.left=0;
	rt2.right=50;
	rt2.bottom=150;

	// normal drawing
	DrawText(hdc, szHello, -1, &rt, DT_LEFT);
	ImageList_DrawEx(himl,sfi.iIcon,hdc,0,50,32,32,0,0,
		ILD_TRANSPARENT);
	FillRect(hdc, &rt2, hbrush);
	SetWindowOrgEx(hdc,-100,0,NULL);

	// displaced drawing
	DrawText(hdc, szHello, -1, &rt, DT_LEFT);
	ImageList_DrawEx(himl,sfi.iIcon,hdc,0,50,32,32,0,0,ILD_TRANSPARENT);
	FillRect(hdc, &rt2, hbrush);
	DeleteObject(hbrush);

The displaced drawing does not display on ReactOS at all, but draws fine on
Windows 2000 or other Windows systems. This isn't just an academic problem,
because Delphi uses SetWindowOrgEx extensively!
