NativeWidgetMacAccessibilityTest doesn't add a test for views::Label yet, so
let's move this in a follow-up.

[Patti Lor, 2016/06/17 05:57:36]

Done.

-  Widget* widget = CreateTopLevelPlatformWidget();
-  gfx::Rect screen_rect(50, 50, 100, 100);
-  widget->SetBounds(screen_rect);
-
-  const base::string16 test_string = base::ASCIIToUTF16("Green");
-  views::Label* label = new views::Label(test_string);
-  label->SetBounds(0, 0, 100, 100);
-  widget->GetContentsView()->AddChildView(label);
-  widget->Show();
-
-  // Accessibility hit tests come in Cocoa screen coordinates.
-  NSRect nsrect = gfx::ScreenRectToNSRect(screen_rect);
-  NSPoint midpoint = NSMakePoint(NSMidX(nsrect), NSMidY(nsrect));
