instead of the origin. This makes YCbCr match the other image types (e.g. RGBA, Gray) in that an image's bounds is not restricted to the positive quadrant. Also optimize the YCbCr draw code by hoisting some computation outside of the loop. benchmark old ns/op new ns/op delta draw.BenchmarkYCbCr 2544418 2373558 -6.72% Like https://golang.org/cl/4681044/ I don't think a gofix is feasible. People will have to make manual changes. On the other hand, directly manipulating YCbCr images is relatively rare, compared to RGBA images, and if other code just uses the jpeg and draw packages instead of messing directly with a YCbCr's []byte representations, then things should just continue to work.

image/draw benchmarks show <1% change for the fast paths. The slow paths got worse by 1-4%, but they're the slow paths. I don't care so much about them, and presumably compiler improvements could claw it back.
