Don’t Include Data Outside of Bounding Box in Downsampling Interpolation

[fm3]

When downsampling data with interpolation, it would be helpful to have an option to exclude data outside of the dataset bounding box. In case of very thin datasets (my example was 15827 × 20271 × 4 vx³) the real data gets mixed with a lot of black data, so downsampled versions become very dark.

~Edit: my bounding box wasn’t set correctly, so I can’t say for sure that this isn’t already the case.~

Are we sure this works? I think, this DS suggests that the original issue still exists: https://scm.slack.com/archives/CMBMU5684/p1691943185180399

The bounding box is set correctly.
