In order to use the overall feedback in assessments of example
submissions and in the assessment form preview, significant improvements
in the rendering machinery were done.
Workshop class provides two new methods overall_feedback_content_options()
and overall_feedback_attachment_options() as they are needed at various
scripts and libraries.
Overall feedback is displayed as a part of the workshop_assessment_form
only if the form is in editable mode (not frozen). If the form is
displayed in read-only (frozen) mode, the caller is expected to render
the overall feedback and list of attachments (the editor and filemanager
elements do not support frozen mode). To do so, the renderable
workshop_assessment now loads overall feedback data and provides two new
methods get_overall_feedback_content() and
get_overall_feedback_attachments() to be used by the renderer.
Renderable workshop_submission, workshop_assessment and related classes
now accept the workshop instance as the first parameter in their
constructors. This way, these renderable classes have access to the
workshop API.
In the future, the rendering of submission files should be improved in
the same way as is done in this patch (i.e. moving the logic and data
preparation out of the renderer into the renderable classes).
Major tasks undertaken in this patch:
* New format_text argument, overflowdiv.
* New page layout Report.
* Review of all format_text calls.
* Added support for the report layout to all themes.
* Changed forum post display from tables to divs.
Important change: teacher's assessments of example submissions (now
known as "reference assessments") are now displayed to students after
they assess example submission.
