1) All slicer's exceptions are now derived from Slic3r::Exception. 2) New exceptions are defined for slicing errors. 3) Exceptions are propagated to the Plater to show. It remains to modify the slicing back-end to throw the new SlicingError exceptions instead of std::runtime_error and to show the other exceptions by a message dialog instead of a notification.
