integer	last_metrics_version = -1
	Fine-level metrics_version at the last refresh, to detect a change.

	When .false., update() does nothing and coarse levels stay frozen at their initial geometry. When .true., update() interpolates the fine-level geometry to the coarse levels.

logical	refresh_eigs = .true.
	Whether a refresh also re-estimates the Chebyshev eigenvalues.

integer	refresh_eigs_frequency = 20
	Re-estimate eigenvalues only every N-th refresh.

logical	eigs_warm_start = .true.
	Restart eigenvalue estimation from the previous eigenvector.

integer	power_its_refresh = 20
	Power iterations used for warm-started re-estimations.

integer	n_refresh = 0
	Refreshes done so far, for refresh_eigs_frequency.

character(len=:), allocatable	cheby_acc
	Which accelerator the Chebyshev smoother uses.
