These texts were never hooked into the test suite, they however
represent a good collection of test texts, but one can always access
them from git history.

Apparently a base glyph can also become an attached component of a
ligature if the ligature-forming lookup used IgnoreBase. This was
being confused with a non-first component of a MultipleSubst and
hence not matched for mark-attachment. Tweak test to fix.

* Shaping tests for Tibetan vowels
* Test-cases for the Dzongkha contractions with multiple vowel-signs added.
* going to be removed
* Extended contraction-test-cases to all test cases in contractions.txt that actually use multiple-vowels (113 cases)
The numbers for right-to-left scripts are processed also from right to
left, so the order of applying “numr” and “dnom” features should be
reversed in such case.

Apparently some clients have reference-table callbacks that copy the table.
As such, avoid loading 'glyf' table which is only needed if fallback positioning
happens.
We use three bits for lig_id these days, so we finally got a report of
two separate ligatures with the same lig_id happening adjacent to each
other, and then the component-handling code was breaking things.
Protect against that by ignoring same-lig-id but lig-comp=0 glyphs after
a new ligature.
