Shouldn't have a copy of Clutter

[Bruce Cowan]

It appears as if this project copies parts of clutter. It shouldn't do this.

[Neil J. Patel (njpatel)]

We require animations which require timelines. Clutter has a great timeline implementation but it, of course, has not been written to also work with Gtk. By taking the timeline code out of clutter and adapting it for Gtk, we don't need to re-invent the wheel.

Of course this means that we would need to track any fixes that the clutter folks have made to the timeline & alpha code, but hopefully Gtk will be getting animations soon, so we can drop EggTimeline in favour of that. If there is interest in the EggTimeline code, it may also be worth to separate it out into it's own library for other developers to use (as the need for animation in Gtk is quite large).

I'm marking this bug as invalid as you haven't provided an alternative to using EggTimeline.

The new notification-daemon does use the timeline and alpha classes of clutter. Why should we not use this proven code-base? It helps speed up the development, avoids reinventing the wheel, makes use of tested code and we credit the originating upstream project. What do you think is wrong with this approach?

What is your reasoning here to discourage that?

I'll try to remember to engage my brain before filing bugs in the future.

More brain does == better bugs, but nevertheless, all bug reports are
appreciated!
