 // performance overhead to enable full accessibility support.

 // Here's how the on-screen keyboard works in Windows 8 "Metro-style" apps:
 //
 // 1. The user touches a control.
 // 2. If the application determines focus moves to an editable text control,
 //    it sends a native focus event, pointing to a native accessibility object

 // Sometimes, touching an element other than a text box will result in a
 // text box getting focus. We want the on-screen keyboard to pop up in those
 // cases, so we "cheat" more and always send the dimensions of the whole
 // window as the bounds of the child object. That way, a touch that leads
 // to a text box getting focus will always open the on-screen keyboard,
 // regardless of the relation between the touch location and the text box
 // bounds.
