Vectorized 4:2:0 subsampling leads to artifacts during Jpeg encoding. #1549

Quality just triggers the subsampling when < 91 so yes, explicitly setting the property would be enough. |

modeDescription
Issue originally identified by @jrdiver in #1547 Thanks for that!
The new vectorized subsampling algorithm introduced in #1517 by @tkp1n is creating artifacts in our jpeg output. Unfortunately our regression tests did not capture the issue.
v1.0.3-alpha.0.28
v1.0.3-alpha.0.29
Steps to Reproduce
Simply resaving the input image is enough ensuring the quality is low enough to trigger 4:2:0 subsampling.
