  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.
