Surely adjusting the region bounds to match the data is better than
adjusting the data (visually) to fit in the region bounds.

The data is sacrosanct. The region bounds are a temporary whim.

As long as the gui window's x,y cursor output etc keeps up to date with
any adjustments, it doesn't seem very problematic to me to slightly
nudge the zoom box to fit the data's resolution before rendering.
