        at least the extent of the metafont ledger_line character, and
        which grows(!) if the desired extent shrinks below this limit.

        later use.
        (quantise_interval): Don't quant to dy steeper that
        least-squares-dy.  Return empty interval if no sane quants found.

        acceptable solution.

2002-03-15  Jan Nieuwenhuizen  <janneke@gnu.org>

        * scm/interface-description.scm (beam-interface): Update.

        * mf/feta-bolletjes.mf: make ledger line rounder. 

        * mf/feta-toevallig.mf: some smallish fixes for flat sign.

        * mf/feta-eindelijk.mf: make 8th rest a little darker, some more
        parametrization.

2002-03-15 Chris Jackson <chris@fluffhouse.org.uk>
 
       * lily/piano-pedal-engraver.cc: Rewritten to support bracketed as
       well as text pedal indications and a combination of both.  All
       pedal indications are horizontally aligned on a line spanner.
 
       * lily/text-spanner.cc: Edge-width property added to use in
       bracketed piano pedals. Function setup_sustain_pedal added to set
       the dimensions of the brackets. 
 
       * scm/grob-description.scm: New *PedalLineSpanner grobs added, and 
       some of the *Pedal properties tweaked. 
 
       * scm/grob-property-description.scm: New pedal-type (*Pedal) and
       edge-width (TextSpanner) properties.
 
       * ly/engraver-init.ly: Default strings added for SostenutoPedal. 
 
       * lilypond-font-lock.el: sostenuto, unaCorda and treCorde added to

        * lily/include/new-beam.hh: Previously new-beam.hh
        * lily/beam.cc: Previously new-beam.cc
        (least_squares): Bugfix: don't barf on beams with less than two
        visible stems (tremolos).

        * scm/beam.scm: 
        * scm/grob-description.scm (Beam): Junk old beam stuff.
        
        
2002-03-14  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

        * VERSION: 1.5.40

        * mf/feta-eindelijk.mf: new 8th rest.

        * mf/feta-toevallig.mf: small fixes for the sharp symbol. Don't
        stick out of staffline

        * scripts/lilypond-book.py: fixes for texi regular expressions.

2002-03-14  Jan Nieuwenhuizen  <janneke@gnu.org>

        * lily/include/new-beam.hh:
        * lily/new-beam.cc: New file.

        * flower/include/interval.hh: 
        * flower/include/interval.tcc (delta): New method.
        (swap): Now public (previously private).
        
        * scm/beam.scm (default-beam-y-quants): Bugfix: lower beam-sit by
        1 staff-line-thickness.  Sadly, this makes dy quanting problems
        (dy quants allowed should depend on actual left y) more visible.

2002-03-13  Jan Nieuwenhuizen  <janneke@gnu.org>

        * lily/beam.cc (quantise_dy): Bugfix: sign (0) = 0.  Hmm.

        * scm/grob-property-description.scm (concaveness-threshold): Add
        typecheck and description.

        * scm/grob-description.scm (Beam): Remove obsolete properties, add
        concaveness-threshold (previously concaveness).

        * lily/beam.cc (check_concave): Remove choices and debugging
        stuff: use best concaveness calculation.
        (quantise_dy): Remove choice.  Try to never make a slope steeper
        by quantising, but certainly never quantise a slope away.
        (check_stem_length_f): Remove choice.  In case of lengthening
        alowed, always lengthen to ideal length.

        * Documentation/index.texi: Fix FAQ url.

        * Documentation/topdocs/INSTALL.texi: Add information about fink,
        compile fix and 1.4 specific fix that doesn't hurt 1.5.

2002-03-13  Han-Wen  <hanwen@cs.uu.nl>

        * VERSION: 1.5.39 released

        * lily/simple-spacer.cc (add_rod): rods take precedence over
        infinitely stiff springs. This fixes bugs with arpeggios and bar-lines.

        * lily/arpeggio-engraver.cc (acknowledge_grob): clean up.

        * lily/note-spacing.cc (get_spacing): only insert space for
        accidentals if necessary.

        * input/regression/spacing-accidental-staffs.ly (texidoc): update example

        * lily/spacing-spanner.cc (musical_column_spacing): new

2002-03-12  Jan Nieuwenhuizen  <janneke@gnu.org>

       * Documentation/topdocs/INSTALL.texi: Add section for MacOS X.

       * darwin.patch: New file.

       * lily/stem.cc (get_default_stem_end_position): Shorten only half
       of shorten value for boundary cases.

       * scm/grob-description.scm (Stem): Set stem-shorten to (1.0 0.5).
       (Beam): Set beamed-stem-shorten to (1.0 0.5).

2002-03-11  Jan Nieuwenhuizen  <janneke@gnu.org>

       * lily/beam.cc (check_stem_length_f): Try to lenthen more.

       * scm/grob-description.scm (Beam): Add concaveness.  Replace
       Beam::cancel_suspect_slope with Beam::check_concave.
 
       * lily/beam.cc (check_concave): Calculate concaveness of beam, and
       set slope to horizontal if concaveness > Beam.concaveness.  This
       handles cases that kludgy cancel_suspect_slope was meant to catch
       very well.
       (cancel_suspect_slope): Remove.

2002-03-12 Rune Zedeler <rune@zedeler.dk>

        * lily/beam.cc lily/stem.cc lily/beam-engraver.cc: allow for
        stemLeftBeamCount and stemRightBeamCount to equal 0.
        Fixes [c8 c4 c8]
      
2002-03-12  Han-Wen  <hanwen@cs.uu.nl>

        * lily/spacing-spanner.cc (breakable_column_spacing): Only do
        fixed spacing for pref matter, if the next column is musical, and
        at the same moment.

        * lily/note-spacing.cc (stem_dir_correction): Use correct
        discretionary for stem-bar spacing.

2002-03-11  Han-Wen  <hanwen@cs.uu.nl>

        * VERSION: 1.5.38 released 

        * lily/grob.cc (warning): Use cause tracking to give more
        meaningful errors from the backend. 

        * lily/property-iterator.cc (check_grob): Warn if setting grob
        property in unknown grob. 

        * mf/feta-toevallig.mf: brushed stems for natural sign.

        * lily/molecule.cc (align_to): don't translate empty molecule.
        (this triggers a very subtle bug in time-signature.)  

2002-03-10  Han-Wen  <hanwen@cs.uu.nl>

        * lily/spring.cc: remove file.

        * input/regression/spacing-stem-bar.ly: new file

        * lily/score.cc (run_translator): resurrect point-and-click

        * input/baerenreiter-sarabande.ly: Copy Barenreiter beaming for
        sarabande layout

        * lily/spacing-spanner.cc (find_shortest): Shortest note for
        spacing is now globally determined, using the most common shortest
        note. Notes that are shorter are spaced geometrically, and with
        expand hints. This makes spacing more even, and measures that have
        very short notes won't be that stretched out.  

        * mf/feta-klef.mf: F-clef fixes, documentation on the
        shape. (WARNING: font changed.)

2002-03-09  Han-Wen  <hanwen@cs.uu.nl>

        prefatory matter is fixed.

2002-03-08  Han-Wen  <hanwen@cs.uu.nl>

        * lily/note-spacing.cc (stem_dir_correction): Correct spacing for
        barline following an upstem.

        * lily/staff-spacing.cc (extremal_break_aligned_grob): destill
        function from next_notes_correction().
        (bar_y_positions): idem.

2002-03-04  Han-Wen Nienhuys  <hanwen@cs.uu.nl>

        left-align molecule.
        
        * lily/break-align-interface.cc (do_alignment): completely
        rewritten. Now it does not use Align_interface anymore, but a
        separate routine. Like StaffSpacing, it reads space-alist from the
        breakable grobs.  This allows you to set spacing using
        
        \property Staff.Clef \override #'space-alist = '(....stuff....)  
 
        * lily/bar-line.cc, lily/include/bar-line.hh: change name from Bar
        to Bar_line. Move files around as well.

        * lily/spacing-spanner.cc: move from third-try.cc; rename
        Third_spacing_spanner to Spacing_spanner.

        * lily/staff-spacing.cc (get_spacing_params): redo prefatory
        spacing stuff. Much cleaner now, and we prepare for neat spacing
        tricks around bar lines and such.

        * lily/third-try.cc (prune_loose_colunms): bugfix. Don't init
        variables with themselves. (Ouch.)

        * lily/span-bar.cc (brew_molecule): don't try to span bars that
        overlap.

        * lily/third-try.cc (do_measure): only take spacings into account
