As discussed in T38340 the solution is to use the current scene from context whenever feasible. Composite does not use node->id at all now, the scene which owns the compositing node tree is retrieved from context instead. Defocus node->id is made editable by the user. By default it is not set, which also will make it use the contextual scene and camera info. The node->id pointer in Defocus is **not** cleared in older blend files. This is done for backward compatibility: the node will then behave as before in untouched scenes. File Output nodes also don't store scene in node->id. This is only needed when creating a new node for initializing the file format. Reviewers: brecht, jbakker, mdewanchand Reviewed By: brecht Differential Revision: https://developer.blender.org/D290
