[mutter] Port to Mutter to Clutter 1.0 API

[Owen Taylor <otaylor src gnome org>]

commit fafb7528277f6833f9a3bbe0b0a827672710fcb6
Author: Owen W. Taylor <otaylor fishsoup net>
Date:   Sat Jun 6 13:14:34 2009 -0400

    Port to Mutter to Clutter 1.0 API
    
    - Use float instead of ClutterUnit
    - clutter_actor_get_size/position() return floats (remove some
      stray usage of these functions in the default plugin as well.)
    - Adapt to cogl_texture_new_from_data() changes
    - Use blend strings to set up multitexturing
    - Remove CLUTTER_UNITS_TO_FLOAT() usage
