      Description

      I attach a test case where SetBrushOrgEx appears to have no effect. I also attach an exe that shows the problem as well as screenshots of the bug. The painting code of the test application is the following (the bug happens in the last two columns):

                  BeginPaint(hWnd, &ps);
                  HBRUSH hbrush = CreatePatternBrush(hbmp);
                  HBRUSH hbrushold = (HBRUSH)SelectObject(ps.hdc, hbrush);
                  
                  //1st column
                  PatBlt(ps.hdc, 0,0, 20, 100, PATCOPY);
                  
                  //2nd column
                  PatBlt(ps.hdc, 40,0, 20, 50, PATCOPY);
                  PatBlt(ps.hdc, 40,50, 20, 50, PATCOPY);
                  
                  //3rd column
                  PatBlt(ps.hdc, 80,0, 20, 50, PATCOPY);
                  SetViewportOrgEx(ps.hdc, 0, 50, NULL);
                  PatBlt(ps.hdc, 80,0, 20, 50, PATCOPY);
                  
                  //4th column
                  SetViewportOrgEx(ps.hdc, 0, 0, NULL);
                  PatBlt(ps.hdc, 120,0, 20, 50, PATCOPY);
                  SetViewportOrgEx(ps.hdc, 0, 50, NULL);
                  PatBlt(ps.hdc, 120,50, 20, 50, PATCOPY);
                  
                  hbrushold = (HBRUSH)SelectObject(ps.hdc, hbrushold);
                  SetViewportOrgEx(ps.hdc, 0, 0, NULL);
       
                  //5th column
                  SetRect(&rc, 160, 0, 180,100);
                  FillRect(ps.hdc, &rc, hbrush);
                  
                  //6th column
                  SetRect(&rc, 200, 0, 220,50);
                  FillRect(ps.hdc, &rc, hbrush);
                  SetRect(&rc, 200, 50, 220,100);
                  FillRect(ps.hdc, &rc, hbrush);
       
                  //7th column
                  SetRect(&rc, 240, 0, 260,50);
                  FillRect(ps.hdc, &rc, hbrush);
                  SetViewportOrgEx(ps.hdc, 0, 50, NULL);
                  SetRect(&rc, 240, 0, 260,50);
                  FillRect(ps.hdc, &rc, hbrush);
                  
                  //8th column
                  SetViewportOrgEx(ps.hdc, 0, 0, NULL);
                  SetRect(&rc, 280, 0, 300,50);
                  FillRect(ps.hdc, &rc, hbrush);            
                  SetViewportOrgEx(ps.hdc, 0, 50, NULL);
                  SetRect(&rc, 280, 50, 300,100);
                  FillRect(ps.hdc, &rc, hbrush);
                  
                  //9th column
                  SetViewportOrgEx(ps.hdc, 0, 50, NULL);
                  SetBrushOrgEx(ps.hdc, 0, 50, NULL);
                  SetRect(&rc, 320, 0, 340,100);
                  FillRect(ps.hdc, &rc, hbrush);
       
                  //10th column
                  SetRect(&rc, 360, 0, 380,50);
                  FillRect(ps.hdc, &rc, hbrush);
                  SetRect(&rc, 360, 50, 380,100);
                  FillRect(ps.hdc, &rc, hbrush);
                  DeleteObject(hbrush);
       
                  EndPaint(hWnd, &ps);
