+ Test if video displays correctly with a 3:2 aspect ratio.
+ It should display at w=150 h=100.
+ On some Linux systems, the scaling to preserve the aspect ratio can sample
+ the pixels outside visible region. This results in a thin grey line down
+ some sides of the scaled picture. We add red bars over the edges to
+ overwrite such happenings, to make the test reliable.
