Change the rule of picking UV mode in MBAnalyzeBestUVMode() Pick the mode with the smallest alpha. It only affects m0, in which case the mode decision is not re-examined later in VP8Decimate(). Tests on some natural content png images show PSNR increase as well as visual quality improvement. Change-Id: Iea997e718cd7477160fa05eb7cfb35f4cec2fa9a
