486	variables used in section 8.5.6.4 are confusing	zhou		"suggest making the following editorial changes to improve the readability. Specifically:
 
–	one (sbWidth + borderExtension) * (sbHeight + borderExtension) prediction sample array predSamplesLX,
–	one (sbWidth * sbHeight) motion vector difference array diffMvLX.
Output of this process is the (sbWidth)x(sbHeight) array pbSamplesLX of prediction sample values.
Variable shift1 is set equal to Max( 6, BitDepthY − 6 ).
For x =0..sbWidth − 1, y =0..sbHeight − 1, the following ordered steps apply:
–	The variables gradientH[ x ][ y ] and gradientV[ x ][ y ] are derived as follows:
gradientHLX[ x ][ y ]  =  ( predSamplesLX[ x + 2 ][ y ] >> shift1 ) − ( predSamplesLX[ x ][ y ] >> shift1 )	(8 796)
gradientVLX[ x ][ y ]  =  ( predSamplesLX[ x ][ y + 2 ] >> shift1 ) − ( predSamplesLX[ x ][ y ] >> shift1 )	(8 797)
–	The variable dI is derived as follows:
dI = gradientHLX[ x ][ y ] * diffMvLX[ x ][ y ][ 0 ] + gradientVLX[ x ][ y ] * diffMvLX[ x ][ y ][ 1 ]	(8 798)
–	Prediction sample value at location ( x, y ) in the subblock is derived as follows:
pbSamplesLX[ x ][ y ] = predSamplesLX[ x + 1 ][ y + 1 ] + ( ( dI + 1 ) >> 1 )	(8 799)
