Functions
	TEST (TestVideoCodecPictureFormat, SquarePixelsAreDisplayedAtThePicturesOwnSize)
	A renderer scales a picture whose display size differs from its own, so neither may be rounded.
	TEST (TestVideoCodecPictureFormat, WidePixelsKeepTheWidthAndReduceTheHeight)
	Pixels twice as wide as they are high: the width is kept and the height halved.
	TEST (TestVideoCodecPictureFormat, AV1ReportsItsPixelFormatAndBitDepth)
	AV1 decodes through libdav1d, which allocates its own frames and so never has sw_pix_fmt set.
	TEST (TestVideoCodecPictureFormat, H264ReportsItsPixelFormatAndBitDepth)
	The get_format() path, which the fallback above must leave alone.
	TEST (TestVideoCodecPictureFormat, RangeNotGivenIsFullForRGBOnly)
	FFmpeg takes RGB to be full range, and a decoder handing RGB over often gives no range.
