Merge "CTS of CtsMediaTestCases#android.media.cts.DecodeAccuracyTest may fail when video is cropped. When we use GPU to copy the data, rendering would choose filter. But we need add shrink in border to ensure the sampler not reach border like what GUI does." am: 06e16941d5 am: 44bfae1759 am: b0838b910c am: ab55cd0ae8
