grayscale_convert() private method

Color conversion for grayscale: just copy the data. This also works for YCC -> grayscale conversion, in which we just copy the Y (luminance) component and ignore chrominance.

private grayscale_convert ( ComponentBuffer input_buf, int input_row, byte output_buf, int output_row, int num_rows ) : void
input_buf	ComponentBuffer
input_row	int
output_buf	byte
output_row	int
num_rows	int
return	void

        private void grayscale_convert(ComponentBuffer[] input_buf, int input_row, byte[][] output_buf, int output_row, int num_rows)
        {
            JpegUtils.jcopy_sample_rows(input_buf[0], input_row + m_perComponentOffsets[0], output_buf, output_row, num_rows, m_cinfo.m_output_width);
        }
