this would be the 3d copy of this code :)

see the comment in render_widget_host_view_views_gtk.cc:
// TODO(oshima): This is a copy from RenderWidgetHostViewGtk. Replace this

If we're gonna reuse this, then I think that function should go into a gtk file
in content. Then we can also one cc file that's included for both gtk + touch
builds that has the :GetDefaultScreenInfo() function, since now it's duplicated
with the one in  render_widget_host_view_gtk.cc.

+// moves to content.
+#if defined(TOUCH_UI)

+// This was copied from render_widget_host_view_views_gtk.cc to make this link;
