Matthew Waters 5ecc3413fd glvideoflip: incorporate the aspect ratio into the scale_x calculations
1. Otherwise rotating the video will clip and show black bars due to
   gltransformation's implementation.
2. The other option of make gltransformation aspect-agnostic produces
   incorrect output with perspective transformations.
