CSSJanus (introduced in [26107]), we had a great time with you, but sadly you don't like our fancy CSS.
RTLCSS is a framework for converting CSS from LTR to RTL, same as CSSJanus, with support for more CSS properties like `transform`, `transition` or multiple box and text shadows.
Changes:
* devDependencies: Remove `grunt-cssjanus`, add `grunt-rtlcss`.
* RTLCSS uses `/* rtl:ignore */` to ignore a rule, switch existing `/* @noflip */` to the new directive.
* RTLCSS supports the `transform` property, means we can remove some ignore rules.
* RTLCSS supports string maps for custom replace rules. This commit includes a rule `import-rtl-stylesheet` which replaces ".css" with "-rtl.css" in URLs.
Notes for core development:
* The file generation task is still `grunt rtl`.
* If you have used `grunt cssjanus` before, use `grunt rtlcss` now.
* Remember the new directive `/* rtl:ignore */`.
fixes#31332.
Build: https://build.trac.wordpress.org/changeset/31554

RTL files are now created on build for core CSS files. These files replace the LTR file completely, rather than being in addition to the existing LTR file.
Benefits:
* For the user: less CSS is served in RTL, less HTTP requests on the frontend, and less work for the browser.
* For the core developer: Let the tools do the work.
Notes for core development:
* The file generation task is `grunt rtl`.
* `grunt watch` now handles generating RTL files in /build when a CSS file in /src is saved.
* /src is now locked to LTR. RTL testing must occur via /build. When attempting to run an RTL text direction with /src, an admin notice will display.
Expect RTL bugs. Please report them.
