Using ci Action #417 AppImage.

Expected Behavior: The selection tool selects all voxels within its box. The size (dimensions) and origin of the box can be set in the tool window.

Observed Behavior: The selection tool will erroneously ignore voxels within the box, and select voxels outside of the box.

I tried selecting the face of this layer with a h value of 1.

It selected a strange shape, the top half had an h value of 4, the bottom had a value of 1.

This is what it looks like after I cut it to a new layer and set the visibility to off.

Another selection test. h is set to 4. Looks good (Except for the bottom):

When increased to 5, it breaks:

Thanks! I just pushed a fix, hopefully this doesn't break anything else.
