The problem was that, if we killed export when some graphic was being converted, or some external template was being handled, it would only cancel that process, and then it would just continue. To deal with that, we need to do a few things: 1. Modify the return values for some of the Converters routines, and similarly the routines for external templates, so we can tell when something has been canceled. 2. Throw an exception from InsetGraphics or InsetExternal when this has happened during export, but ONLY when the Buffer is a clone. We shouldn't be able to 'cancel' export when we're, say, generating code for the preview pane, but this keeps us on the safe side.. The exception then has to be caught, obviously, back in the export routines in Buffer. Probably Coverity will be unhappy about something here, but I'll deal with that problem as it arises.
