(v13) Job and skin timelines

This page applies to Harlequin v13.1r0 and later; both Harlequin Core and Harlequin MultiRIP

This is another change that is of interest to OEMs performing complex integrations. There are now timelines for both the skin overall (SWTLT_SKIN) and the submitted job as seen by the skin (SWTLT_SKIN_JOB). The skin timeline is a parent of the RIP core timeline, and so is navigable via SwTimelineOfType() from any RIP callback function that presents a timeline. This allows contextual information attached to the timeline using SwTimelineSetContext() and SwTimelineGetContext() to be accessed cleanly, in a thread-safe manner, from any code that can access a valid timeline reference.

The SWTLT_SKIN_JOB timeline is of interest, because it provides a clear scope for the RIPping of a file, as well as the job number as set by the skin (attached to the SW_SKIN_JOB_NUMBER_CTXT context) and the name of the file as submitted to the RIP (in the timeline title). Event handlers that detect the start and end of this timeline can be used to determine when the RIP is processing a particular job submitted by the skin.
