[Dev-luatex] Snapshot 20070426

Hi all,

This past month I have been busy with nodes and lists of nodes,
so the big new feature in this release is that there are four
callbacks that operate on node lists:

   buildpage_filter
   pre_linebreak_filter
   hpack_filter
   vpack_filter

The preliminary documentation for these is in the manual, but the basic
idea is that you can filter a node list just before LuaTeX starts doing
something with it (like line breaking). This functionality is not stable
yet: the node presentation of the various node types is pretty much OK
now, but keep in mind the following:

   * math noads and math typesetting are not handled at all (yet)
   * not all hpacks and vpacks are intercepted (yet)
   * the nested node list handling will probably change
   * A conversion tool for nodes to/from dictionaries is planned,
     but not done yet

The other changes in this snapshot are various bugfixes (for builds
on various platforms as well as font issues) and speedups (in the 
execution of callbacks and the creation of lua font representations).

Have fun,
Taco

Downloading and installation details:

If you go to

         https://foundry.supelec.fr/frs/?group_id=10

you will see that there are three new released files:

* luatex-snapshot-20070426.tar.bz2
         This is the source tree.

* luatex-snapshot-20070426-win32.zip
         A cross-compiled (mingw) windows binary. This is a web2c
         based binary, so it needs a texmf.cnf file (It will NOT
         work if you have only miktex installed).

* luatex-snapshot-20070426-linux-i386.tar.bz2
         An intel 32 linux binary (very new gcc/libc)
