Strengthen bounds check in CWeightTable::Calc.
The buffer PixelWeight.m_Weights was allocated by calling FX_TryAlloc(uint8_t, m_dwWeightTablesSize),
but PixelWeight.m_Weights was an int array. Thus bounds check such as |if (idx >= m_dwWeightTablesSize)|
in function CWeightTable::Calc() and |idx < m_dwWeightTablesSize ? &pWeight->m_Weights[idx] : nullptr|
in function CWeightTable::GetValueFromPixelWeight() were insufficient.
This CL strengthens bounds check for accessing int type array PixelWeight.m_Weights.
