In function TComUpsampleFilter::upsampleBasePic(), the vertical upsampling of chroma has an error. Variable scaleX is inocrrectly being used in place of scaleY.

Existing code looks like this:

#if R0209_GENERIC_PHASE
      refPos16 = (((y - srlTOffsetC)*scaleX - addY) >> shiftYM4) + refOffsetYC;
#else

Corrected code should look like this:

#if R0209_GENERIC_PHASE
      refPos16 = (((y - srlTOffsetC)*scaleY - addY) >> shiftYM4) + refOffsetYC;
#else
