-<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>
