hairpin: start at left edge of a rest
small padding adjustment; issue 3630
script-column: earlier scripts support later scripts; issue 3683
Reduce offsets of \super and \sub

This brings chordNames and text superscripts into better agreement
with the shifts in user-provided scans.
Completion_*_engraver: add means to preserve scale factor; issue 3650
Make music-drawing-routines.ps require PostScript 2.0

There is no point having conditional code around setstrokeadjust and
its ilk any more.
Make stroke_and_fill? PostScript operator that fills conditionally
Don't meddle with Ghostscript's choice of currentstrokeadjust

It should be appropriate for device and resolution by default.
Issue 2658: Be serious about setstrokeadjust in PostScript primitives

This particularly concerns draw_round_box which is used for drawing
lines with a rounded ending.  If the width/height ratio or its inverse
exceeds 2, the box is considered to be a "line".  In this case, first
a clipping path is established representing the whole shape and
extended widely in the area of the "main stroke".  The reason for this
extension is to avoid both clip area and stroke competing for the
outline.  While this is not a problem for the PostScript or PDF
rendering model, the Cairo bitmap rendering library employs
Porter-Duff compositing for antialiasing amounting to "cheap man's
antialiasing" not requiring a higher rendering resolution but relying
on edges affecting a single pixel to be independent.

Porter-Duff requires us not to have multiple parallel strokes or clip
areas if we want to avoid wrong sub-pixel grayness levels (and
consequently lines appearing too thick or thin) in Cairo-based
previewers like Evince.

After establishing the clip area, a stroke is drawn through.  This
stroke may (at the PostScript device's discretion) employ
strokeadjustment further correcting the apparent thickness.
Ghostscript employs stroke adjustment when rendering at a resolution
below 150dpi.  Stroke adjustment does not pass into PDF, however, when
ps2pdf runs.

Ghostscript performs sub-pixel rendering for antialiasing which
reduces the amount of discontinuities possibly caused by joining
stroke-adjusted shapes with full shapes.

It turns out that sharper contours can be achieved by using strokepath
and fill instead of a plain stroke.  However, the resulting crisper
stems tend to combine worse with beams, so this approach has not been
pursued.
Implement option -dstrokeadjust in order to get stroked stems and strokeadjustment

This makes the stroke drawing primitives for long rounded rectangles
dependent on the setting of currentstrokeadjust.  As a result,
low-resolution bitmap devices (up to 150 dpi or so) will get stroke
adjustment applied automatically.  The option needs to get invoked
explicitly to get stroke adjustment for PDF, giving a large file size
increase and markedly better previews on a number of PDF previewers.
Add Changes entry for -dstrokeadjust and "Usage" entry.

Issue 3695: Fix LILF table in emmentaler

From <URL:http://lists.gnu.org/archive/html/bug-lilypond/2013-11/msg00113.html>:

Now, for recent versions of emmentaler (same font file), LILC contains:
  (subfont . "feta20")
  (subfont . "feta-alphabet20")
  (subfont . "feta-flags20")
  (subfont . "feta-noteheads20")
  (subfont . "parmesan20")
  (subfont . "parmesan-noteheads20")

[...]

but the subfonts array has not been updated in
these commits.
Issue 3706: Allow computed identifiers for \change

This makes it possible to write

\change #'Staff = #"high"

(or other computed expressions) just like it is possible with

\new #'Staff = #"high" { ... }

CG: remove information about frogs and frog meister

frogs list is dead, and the frog meister was a good idea
but it gets out of touch from reality (since a few months
previous Frog Meister didn't actually participate in development).
