%D \module
%D [ file=type-otf,
%D version=2007.07.30,
%D title=\CONTEXT\ Typescript Macros,
%D subtitle=Stix,
%D author=Hans Hagen,
%D date=\currentdate,
%D copyright={PRAGMA ADE \& \CONTEXT\ Development Team}]
%C
%C This module is part of the \CONTEXT\ macro||package and is
%C therefore copyrighted by \PRAGMA. See mreadme.pdf for
%C details.
%D We provide typescripts for version one and two of the stix fonts. There is a
%D xits variant based on the first (not opentype) release that also provides
%D bidirectional math. With (in 2022) stixtwo being frozsen for 2 years we can make
%D these the default now.
%D
%D Users should be aware of the fact that the stix filenames keep changing so if
%D something fails, make sure you have the files and that the names below match
%D those on your system. In \TEX\ distributions there's 2 and Two and math can have
%D -Regular appended or not. You can expect the \CONTEXT\ distribution to be kept up
%D to date.
%D
%D Per november 2022 we swithched from \OPENTYPE\ (otf) files to \TRUETYPE\ (ttf)
%D files. The main reason is that the metrics are cleaner, especially when one peeks
%D into the font for the purpose tweaking math (boundingbox, true positioning
%D unaffected by excessive hinting shown in in FontForge). It is yet unclear to us
%D (MS & HH) why there is this difference, but it might relate to the toolchain used
%D for generating these fonts. We might even switch to (smaller) unhinted \TRUETYPE\
%D fonts at some point but then we need to generate them ourselves). Anyway, the end
%D results are the same but we just want to be able to view it right.
