I implemented and pushed a test version of this. Please let me know if
it works for you.

To use it, if you have a video with hard coded black borders, go to
Preferences->Current Video and select the real aspect ratio of the
video from the "Crop to aspect ratio" box. Bino will remove the borders
accordingly, and zoom mode will work as expected.
