-// Generates YUV420 frames with a "landscape with striped crosshair" in the
-// Y-plane, plus a horizontal gradient in the U-plane and a vertical one in the
-// V-plane. This makes for a nice mix of colours that is suited for both
-// catching visual errors and making sure e.g. YUV->RGB/BGR conversion looks
-// the same on different platforms.
-// There is also a solid box bouncing around in the Y-plane, and two differently
-// coloured lines bouncing horizontally and vertically in the U and V plane.
-// This helps illustrating how the frame boundary goes, and can aid as a quite
-// handy visual help for noticing e.g. packet loss if the frames are encoded
-// and sent over the network.
