  - Maximize vertically if pointer reaches top or bottom edges.
  - Explicitly depend on resize-options. (LP: #1039834)
  - Add some docstring warnings about using those classes directly.
  - Fix some memory management issues on the mock objects, namely:
    Make destructor functions virtual where appropriate, so that we can add 
    them to lists polymorphically. Support polymorphic ccs*Unref function.
    Also make some other necessary changes to libcompizconfig.
  - Detect if rsvg 2.36.2 is installed (LP: #1039843)

    the integration code to make it more flexible. (LP: #1035261)
