The ID3DXMatrixStack::Scale method determines the product of the current matrix and the computed scale matrix composed from the given point (x, y, and z).
HRESULT Scale( float x, float y, float z );
This method returns S_OK.
This method right-multiplies the current matrix with the computed scale matrix (transformation is about the current world origin):
    D3DXMATRIX tmp;
    
    D3DXMatrixScaling( &tmp, x, y, z );
    m_stack[m_currentPos] = m_stack[m_currentPos] * tmp;
