[Aarto Matti <aarto matti gmail com>]

Hello,

I receive an  error: "‘class Clutter::Timeline’ has no member named ‘set_n_frames’". This methods is listed  in both documentation and sources
http://www.gtkmm.org/docs/cluttermm-0.9/docs/reference/html/classClutter_1_1Timeline.html

http://git.gnome.org/cgit/cluttermm/tree/clutter/src/timeline.hg

but not  in include/cluttermm-0.9/cluttermm/timeline.h.

How it can be?
