// We need to find a way to call SDL_VideoModeOK *before*
// that happens and revert to all the old settings if we
// can't pull off the switch to the new settings.
//
// Fingolfin says: the "easy" way to do that is not to modify
// the member vars before we are sure everything is fine. Think
// of "transactions, commit, rollback" style... we use local vars
// in place of the member vars, do everything etc. etc.. In case
// of a failure, rollback is trivial. Only if everything worked fine
// do we "commit" the changed values to the member vars.
