Currently, the GPU image decode path doesn't support yuv. In order to add yuv support the Skia API getDeferredTextureImageData will need to be updated to support decoding yuv.
Due to slight rounding differences in the yuv/non-yuv decode paths, turning on the GPU image decode controller causes slight differences in layout tests which used yuv decode.
This bug tracks re-enabling yuv and updating the layout tests again.
