Motion vector storage for GPM mode

Description

Equations 1043 to 1051 are missing an offset for the coding block position in the picture (xCb and yCb).

MvL0[ ( xSbIdx << 2 ) + x ][ ( ySbIdx << 2 ) + y ] = mvL0 (1043)

The index ranges above are all within the coding block, so there is no picture-level position.

x = 0..3
y = 0..3
xSbIdx = 0..numSbX − 1
ySbIdx = 0..numSbY − 1

Good catch, thank! This will be fixed in JVET-S2001-vH by changing the range of x and y as follows:
x = xCb..xCb + 3 and y = yCb..yCb + 3.
