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.
