This patch appears to include an additional change in passing
screenInfo.x + screenInfo.width and screenInfo.y + screenInfo.height
instead of just screenInfo.width and screenInfo.height.

If this is essential to the fix noted above, please make sure the change
is described in the commit log. If it is a separate fix, please create a
separate patch for it.
