OK, I updated Metal and Synth L&F.

The test in this PR does not currently test either of these new changes, though. Normally I'd feel nervous about that, but IMO the changes in this PR are acceptably low-risk.

Does anyone disagree? If so: should I split this into 2-3 separate tickets/PRs? The original steps involved the Windows L&F and changing the OS's accessibility contrast settings; I don't know if those steps affect Metal/Synth L&F's at all.
