697	Mismatch of equation (8-1261) between VTM and spec	nanhu		"In spec, equation (8-1261) is
avgVar[ x ][ y ] = varTab[ Clip3( 0, 15,		
	( sumOfHV[ x >> 2 ][ y >> 2 ] * ac[ x >> 2 ][ y >> 2 ] ) >> ( 3 + BitDepth ) ) ].

However, in VTM, when calling the method m_deriveClassificationBlk, the input shift is set as m_inputBitDepth[CHANNEL_TYPE_LUMA] + 4, which means
the value is right shifted by ( BitDepth + 4 ).

Suggest to align spec with VTM ( using BitDepth + 4 in (8-1261) ).
