Rather than hardcoding the size and presence of the notification area in Dart, we now expose padding values on the view. These values are set to non-zero values when there are UI elements that overlap the view. We currently respect only the top padding, but this CL paves the way to respect padding in other directions. We still hardcode the size of the notification area in Java. A future CL will retrieve this value from the Android framework. Fixes #257 R=ianh@google.com Review URL: https://codereview.chromium.org/1220353002.
