d2608583	2023-01-05T10:51:12	TurboJPEG: Ensure 'pad' arg is a power of 2 Because the PAD() macro can only handle powers of 2, this is a necessary restriction (and a documented one, except in the case of tjCompressFromYUV()-- oops.) Failing to check the 'pad' argument caused tjBufSizeYUV2() to return bogus results if 'pad' was less than 1 or otherwise not a power of 2. tjEncodeYUV3() and tjDecodeYUV() effectively treated a 'pad' value of 0 as unpadded, but that was subtle and undocumented behavior. tjCompressFromYUV() did not check whether 'pad' was a power of 2, so the strides passed to tjCompressFromYUVPlanes() would have been incorrect if 'pad' was not a power of 2. That would not have caused tjCompressFromYUV() to overrun the source buffer, as long as the calling application allocated the buffer based on the return value of tjBufSizeYUV2() (which computes the strides in the same manner as tjCompressFromYUV().) However, if the calling application attempted to initialize the source buffer using correctly-computed strides, then it could have overrun its own buffer in certain cases or produced incorrect JPEG images in others. Realistically, there is no reason why an application would want to pass a non-power-of-2 'pad' value to a TurboJPEG API function, so this commit is about user-proofing the API rather than fixing any known issue.

Effectively, it has had that behavior all along, but the API does not guarantee that tjFree() will be implemented with free() behind the scenes, so it's best to formalize the behavior.
