Blender Version
Broken: 2.80 alpha 2, hash: f520f01b46b

Short description of error
I've only tried the texture node in the compositor but it's possible other nodes are affected too. So when rendering animation, if I try to animate a property on the Texture node in the compositor say (offset) - check attached blender file - the property doesn't actually get updated as the time progresses.

Exact steps for others to reproduce the error
Try to render animation (ctrl f12) and check to see that it's the same image when the texture should be animated via the Offset.Z property of the Texture node.

etc... nothing else though

BUT: would expect something from the [RENDER] like (when e.g. transform is animated):

[RENDER]: Operation is entry point for update: TRANSFORM_LOCAL()
[RENDER]: Operation is entry point for update: COPY_ON_WRITE()

@Sergey Sharybin (sergey): one for you?

Technically, @Brecht Van Lommel (brecht) is the boss of render pipeline.

From a developer's point of view, i do not see any calls to DEG_evaluate_on_framechange(). So my guess is that this is something where old dependency graph had hacks to do animation evaluation directly in various places.
