2016-10-17lcms: reject NaN when reading float numberskcwu
LerpFloat functions expect input values are normal float. They first clamp values to the range of [0.0, 1.0] and then calculate interpolation with the input values. If the input value is NaN, it will lead to heap buffer overflow because the index to LutTable is calculated based on the said value and fclamp(NaN) is not in expected [0.0, 1.0] range. This patch rejects all NaN values earlier when reading float numbers. So it also changed behavior for cases other than LerpFloat. I think it is okay because NaN doesn't make sense for usual calculations. BUG=654676 Review-Url: https://codereview.chromium.org/2422553002
