mGBA 0.9.0 Introduces Lighting Offset in F-Zero: Maximum Velocity

[CLS-StarkThyme]

mGBA 0.9.0 introduced something very unusual. This does not apply to Falcon Densetsu (GP Legend) or Climax (from what I saw), so it is exclusive to Maximum Velocity. What I noticed is that the lighting on the track was shifted downward by one pixel. Again, while very minor, I spotted it most easily on Tenth Zone East: Snake Circuit.

Upon further analysis by disabling certain background and object layers, it became apparent that a single-row line was stretched to fill two pixel rows.
