Scrolling in higher mip levels

I noticed that at non-zero mip levels every movement in z (either using mouse wheel or keyboard shortcut) still corresponds to movement of one slice at mip 0. This makes scrolling choppy at higher mip levels if the volume is downsampled isotropically. Would be possible to provide a configuration option to allow scrolling `current_res/full_res` number of full-resolution slices (i.e. always one voxel per scroll regardless of voxel resolution) at a time so that scrolling will be smooth?
