Detailed Description

Track one asynchronous Cairo surface fetch request for a GUI widget.

The fetcher owns the background job bookkeeping and the current cached surface metadata. The actual Cairo surface remains owned by the caller through the target pointer passed to dt_view_image_get_surface_async().
