        Function Name: dct

        Operation: Find the 8x8 DCT of an array using separable DCT

        First, finds 1-d DCT along rows, storing the result in inter[][]

        Then, 1-d DCT along columns of inter[][] is found

        Input: pixels is the 8x8 input array

        Output: dct is the 8x8 output array
