	specific compare functions used in encoding, it depends upon the command line
90 90
        switches which of these are used
91 91
        dont waste ur time with dct_sad & quant_psnr they arent really usefull

put_pixels_clamped / add_pixels_clamped
94
	used for en/decoding, easy

	used for en/decoding in the IDCT, easy
95
        Note, some optimized IDCTs have the add/put clamped code included and then
