Use a consistent, readable format for all initializers. This layout facilitates the next several patches, which implement Effective C++ recommendations and remove compiler warnings. The layout also works with the astyle settings in the reindent script. Signed-off-by: Ray Lehtiniemi <rayl@mail.com> svn path=/trunk/kdenlive/; revision=3225
