This builds on bug 1428676 and introduces StyleAppearance, which replaces the NS_THEME_* constants. Really sorry for the size of the patch. There's a non-trivial change in the gtk theme, which I submitted separately as bug 1478385. Differential Revision: https://phabricator.services.mozilla.com/D2361 MozReview-Commit-ID: DiSmMWK7Krp
