-implement a few helper functions. These functions are rather optimized.</p>
---ldx]]--
-
---[[ldx--
-<p>When manipulating node lists in <l n='context'/>, we will remove
-nodes and insert new ones. While node access was implemented, we did
-quite some experiments in order to find out if manipulating nodes
-in <l n='lua'/> was feasible from the perspective of performance.</p>
-
-<p>First of all, we noticed that the bottleneck is more with excessive
-callbacks (some gets called very often) and the conversion from and to
-<l n='tex'/>'s datastructures. However, at the <l n='lua'/> end, we
-found that inserting and deleting nodes in a table could become a
-bottleneck.</p>
-
-<p>This resulted in two special situations in passing nodes back to
-<l n='tex'/>: a table entry with value <type>false</type> is ignored,
-and when instead of a table <type>true</type> is returned, the
-original table is used.</p>
-
-<p>Insertion is handled (at least in <l n='context'/> as follows. When
-we need to insert a node at a certain position, we change the node at
-that position by a dummy node, tagged <type>inline</type> which itself
-has_attribute the original node and one or more new nodes. Before we pass
-back the list we collapse the list. Of course collapsing could be built
-into the <l n='tex'/> engine, but this is a not so natural extension.</p>
-
-<p>When we collapse (something that we only do when really needed), we
-also ignore the empty nodes. [This is obsolete!]</p>

-<p>At some point we ran into a problem that the glue specification
-of the zeropoint dimension was overwritten when adapting a glue spec
-node. This is a side effect of glue specs being shared. After a
-couple of hours tracing and debugging Taco and I came to the
-conclusion that it made no sense to complicate the spec allocator
-and settled on a writable flag. This all is a side effect of the
-fact that some glues use reserved memory slots (with the zeropoint
-glue being a noticeable one). So, next we wrap this into a function
-and hide it for the user. And yes, LuaTeX now gives a warning as
-well.</p>

-<p>The fontforge table has organized lookups in a certain way. A first implementation
-of this code was organized featurewise: information related to features was
-collected and processing boiled down to a run over the features. The current
-implementation honors the order in the main feature table. Since we can reorder this
-table as we want, we can eventually support several models of processing. We kept
-the static as well as dynamic feature processing, because it had proved to be
-rather useful. The formerly three loop variants have beem discarded but will
-reapear at some time.</p>
-
-<itemize>
-<item>we loop over all lookups</item>
-<item>for each lookup we do a run over the list of glyphs</item>
-<item>but we only process them for features that are enabled</item>
-<item>if we're dealing with a contextual lookup, we loop over all contexts</item>
-<item>in that loop we quit at a match and then process the list of sublookups</item>
-<item>we always continue after the match</item>
-</itemize>
-
-<p>In <l n='context'/> we do this for each font that is used in a list, so in
-practice we have quite some nested loops.</p>
-
-<p>We process the whole list and then consult the glyph nodes. An alternative approach
-is to collect strings of characters using the same font including spaces (because some
-lookups involve spaces). However, we then need to reconstruct the list which is no fun.
-Also, we need to carry quite some information, like attributes, so eventually we don't
-gain much (if we gain something at all).</p>
-
-<p>Another consideration has been to operate on sublists (subhead, subtail) but again
-this would complicate matters as we then neext to keep track of a changing subhead
-and subtail. On the other hand, this might save some runtime. The number of changes
-involved is not that large. This only makes sense when we have many fonts in a list
-and don't change to frequently.</p>

--- this is still somewhat preliminary and it will get better in due time;

--- of Idris Samawi Hamid to who we dedicate this module.
-
--- some day when we can jit this, we can use more functions
-
--- we can use more lpegs when lpeg is extended with function args and so
--- resolving to unicode does not gain much
-
--- in retrospect it always looks easy but believe it or not, it took a lot
--- of work to get proper open type support done: buggy fonts, fuzzy specs,
--- special made testfonts, many skype sessions between taco, idris and me,
--- torture tests etc etc ... unfortunately the code does not show how much
--- time it took ...
-
--- todo:
---
--- kerning is probably not yet ok for latin around dics nodes
--- extension infrastructure (for usage out of context)
--- sorting features according to vendors/renderers
--- alternative loop quitters
--- check cursive and r2l
--- find out where ignore-mark-classes went
--- remove unused tables
--- slide tail (always glue at the end so only needed once
--- default features (per language, script)
--- cleanup kern(class) code, remove double info
--- handle positions (we need example fonts)
--- handle gpos_single (we might want an extra width field in glyph nodes because adding kerns might interfere)

---[[ldx--
-<p>This module is a bit more split up that I'd like but since we also want to test
-with plain <l n='tex'/> it has to be so. This module is part of <l n='context'/>
-and discussion about improvements and functionality mostly happens on the
-<l n='context'/> mailing list.</p>
-
-<p>The specification of OpenType is kind of vague. Apart from a lack of a proper
-free specifications there's also the problem that Microsoft and Adobe
-may have their own interpretation of how and in what order to apply features.
-In general the Microsoft website has more detailed specifications and is a
-better reference. There is also some information in the FontForge help files.</p>
-
-<p>Because there is so much possible, fonts might contain bugs and/or be made to
-work with certain rederers. These may evolve over time which may have the side
-effect that suddenly fonts behave differently.</p>
-
-<p>After a lot of experiments (mostly by Taco, me and Idris) we're now at yet another
-implementation. Of course all errors are mine and of course the code can be
-improved. There are quite some optimizations going on here and processing speed
-is currently acceptable. Not all functions are implemented yet, often because I
-lack the fonts for testing. Many scripts are not yet supported either, but I will
-look into them as soon as <l n='context'/> users ask for it.</p>
-
-<p>Because there are different interpretations possible, I will extend the code
-with more (configureable) variants. I can also add hooks for users so that they can
-write their own extensions.</p>
-
-<p>Glyphs are indexed not by unicode but in their own way. This is because there is no
-relationship with unicode at all, apart from the fact that a font might cover certain
-ranges of characters. One character can have multiple shapes. However, at the
-<l n='tex'/> end we use unicode so and all extra glyphs are mapped into a private
-space. This is needed because we need to access them and <l n='tex'/> has to include
-then in the output eventually.</p>
-
-<p>The raw table as it coms from <l n='fontforge'/> gets reorganized in to fit out needs.
-In <l n='context'/> that table is packed (similar tables are shared) and cached on disk
-so that successive runs can use the optimized table (after loading the table is
-unpacked). The flattening code used later is a prelude to an even more compact table
-format (and as such it keeps evolving).</p>
-
-<p>This module is sparsely documented because it is a moving target. The table format
-of the reader changes and we experiment a lot with different methods for supporting
-features.</p>
-
-<p>As with the <l n='afm'/> code, we may decide to store more information in the
-<l n='otf'/> table.</p>
-
-<p>Incrementing the version number will force a re-cache. We jump the number by one
-when there's a fix in the <l n='fontforge'/> library or <l n='lua'/> code that
-results in different tables.</p>
