Subject: clutter-timeline: Emit the new-frame signal even on the first frame
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5c0aaf50a7b3d1914d4580d5f853faa9a4b10f73;p=profile%2Fivi%2Fclutter.git

clutter-timeline: Emit the new-frame signal even on the first frame

ClutterTimeline has special handling for the first time do_tick is
called which was not emitting a new-frame signal. This meant that an
application which directly uses the timeline would have to manually
setup the initial state of an animation after starting a timeline to
avoid painting a single frame with the wrong state. It seems to make
more sense to instead emit the new-frame signal so that the
application always sees a new-frame when the progress changes before a
paint.
