Hi Jakob,
Thanks for the pointer to those two parameters, that was very helpful.

But I want solutions to be feasible only if they are *worse* (or equal) to
objlimit, so I can't see how I can use SCIPsetObjlimit(scip, objlimit).
Perhaps I should call
SCIP_CALL( SCIPupdateLocalLowerbound(subscip, lowerbound) );
after working out what "lowerbound" should be. (Have to deal with offset
and scale.) What do you think?
