VideoPlacement

Remarks

⚠ Two answers rather than one, because the two scalings need different halves. Contain shrinks the rectangle and leaves the texture coordinates alone; Cover keeps the rectangle and crops the coordinates. A helper that returned only a rectangle could not express the second, and one that returned only coordinates would have to paint the letterbox bars itself — which is wrong the moment the video is drawn over something, because those bars are opaque black over whatever was behind.
