Problem/Motivation
- Some CKEditor plugins need additional CSS to function. E.g. image captions, alignment, etc.
- Loading additional CSS in CKEditor iframe instances currently requires
hook_ckeditor_css_alter()to be implemented. - This means a CKEditor plugin is not able to encompass everything it does: some CKEditor plugins need both a plugin implementation and a hook implementation.
Conclusion: this is a gap in the current API.
Proposed resolution
Fortunately, CKEditor plugins are already built on composed interfaces. So, the mere addition of a CKEditorPluginCssInterface will be sufficient. Any module is then free to adopt this. This is therefore a pure API addition, not even a feature addition, and can therefore go in 8.0: it does not have to wait for 8.1.
Remaining tasks

None.
API changes
None. Pure API addition.
