[feaLib] Emit context-free contextual chains to SinglePos Before this change, we had only emitted a SinglePos (GPOS type 1) lookup for a statement like `pos A' B' 20`; after this change, we always emit a chain rule even if there is no context. There is a semantic difference if the rule is preceded by a `ignore pos` statement. Omitting context-free contextual chains was actually not a (premature) optimization, but an artifact that came from the representation of glyph patterns. https://github.com/behdad/fonttools/issues/516 2016-02-09 08:58:18 +01:00			`# OpenType Feature File specification, section 6.h.iii, example 3d:`

Add fea generation support (#776) * First round of adding fea output No format tests but all test files give reasonable output so far. * Get existing tests working * Initial tests that work for fea2fea * Get more tests working Bug fixes and re-layout some tests to compare with fea2fea output. Ranges and name parameters are not optimised yet. * Handle vertical default values in fea2fea * Hide fea2fea differences in lookupflags * No reduce() in py3 so use a for loop 2016-12-20 10:10:29 +00:00			`pos L' quoteright' -150;`
