SuperMessageAndroidHandlesDocumentLayer class
A document layer that displays an Android-style caret, and positions Leaders for the Android
collapsed and expanded drag handles.
This layer positions and paints the caret directly, rather than using Leaders and Followers,
because its position is based on the document layout, rather than the user's gesture behavior.
