Subject: [PATCH 01/18] Import tests for html ruby extensions

These cover:
* permutations of the allowed syntax for ruby base markup (with or
  without rb, interleaved and tabular markup)
* usage of rt alone, rtc alone, and rt with rtc, and variants where
  (some) rt are implied
* spanning annotations using rtc
* multi-level ruby using rtc (both spanning and non-spanning)
* the presence of rp, and the lack of interference with segmentation and
  pairing, not only when rp respect the content model, but even when it
  doesn't
* inter-element spaces not interferring with segmentation and pairing

See the README for some more info on the approach followed.

+# Tests for HTML Ruby Markup extensions
+
+Specification: https://www.w3.org/TR/html-ruby-extensions/
+
+These tests are hard to write reliably,
+because without relying on a styling mechanism (which should be tested separately),
+there's no prescribed rendering,
+yet the rendering is how we can tell whether the markup did the right thing:
+ruby must be segmented correctly,
+and the correct ruby annotation must be paired with the correct base.
+That is something you can tell visually.
+
+The approach taken here follows the same logic
+as the pre-existing html/semantics/text-level-semantics/the-ruby-element/ruby-usage.html:
+use a mismatch ref-test against what the rendering is likely to be
+if the browser didn't do anything, or did the wrong thing.
+In that original example, the mismatch reference is simply what you'd get in a browser with no support for ruby at all.
+The tests in this directory do that too,
+and add a few variants of possible wrong renderings,
+some attested in existing layout engines,
+some "just in case".
+
+As such, automated test failures are indicative of something being wrong with the implementation,
+but tests passing could be false positives:
+maybe it is implemented right,
+or maybe it is implemented wrong in a novel way.
+
+Therefore, each test is written including a description of the pass condition,
+in a way that can be evaluated by a person looking at the test.
+
+It would be better to write these tests so that their pass condition can be automated,
+but as far as I can tell,
+that's not reliably doable.
+
+For instance, it might be tempting to use `<ruby>X<rt>1</rt>Y<rt>2</rt></ruby>`
+or `<ruby>X<rt>1</ruby><ruby>Y<rt>2</ruby>`
+as a reference for `<ruby><rb>X<rb>Y<rt>1<rt>2</ruby>`
+as they are defined to have the same base/annotation pairing,
+but it is not required that they have precisely the same rendering.
+And indeed, some implementations do vary
+(notably in terms of base/annotation alignment).
+
+So we're left with semi-manual tests.
+
+Anyone finding false positives is encouraged
+to add corresponding mismatch references.

 Specification: https://www.w3.org/TR/html-ruby-extensions/
 
+WARNING: These are manual tests.
+There is some support for automation,
+but the results must be evaluated manually.
+Simply relying on automated reports of tests passing is not sufficient.
+
 These tests are hard to write reliably,
 because without relying on a styling mechanism (which should be tested separately),
 there's no prescribed rendering,

+<p>The example below consists of 3 base characters, each annotated individually, and also all jointly annotated.
+“<span class=r1>あ</span>” is annotated by “<span class=r1>1</span>”.
+“<span class=r2>い</span>” is annotated by “<span class=r2>2</span>”.

+The whole is annotated with “altogether”.
+For ease of comparison, it is preceded by some context text: “例文は”.
+This test passes if:
+<ul>
+    <li>each base character is presented inline with and similarly to the context text, as if they are all part of the same sentence, and
+    <li>each annotation is convenyed as an annotation, and
+    <li>the correct annotation is presented clearly as being associated with the correct base, and
+    <li>the joint annotation is associated with the whole base, not just a part.

+<p>Note: The colors are not part of the test,
+they are merely provided as help to the person runing the test,
+to make it easier to recongnize the various parts of the text.

+The precise appearance is not specified,
