Subject: Re-order OpenType lookups to be more sensible
X-Git-Tag: bedstead-002.007~40
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~bjharris/git?a=commitdiff_plain;h=6700ff36722343c887cc4c214a957ae9ae8e3ed3;p=bedstead-debian.git

Re-order OpenType lookups to be more sensible

The small-caps and 'rtlm' lookups now come before the stylistic sets.
This is appropriate because the former make changes to the semantics
of characters and so should take priority over mere stylistic changes.
'palt' comes last because it can only reasonably be applied to the
actual glyphs being rendered.
