histogram tick drawing - added format generation for optimum tick drawing
Fixes bug #45192 which showed up in the gtk3 branch on MacOS.
It replaces the decimal_xxx computations with a routine that computes a
formatting string and a scale factor for a given axis range and number of
bins. The formatting will switch between normal and scientific depending on
the length of the displayed label text. The formatting is such that no
rounded numbers like 3.9999999 when in fact 4 is expected is shown.
Differences between bins remain visible in the tick labels.
In addition the width of the rendered labels is compared with the width
of the bins in the display such that the labels will automatically
switch between horizontal and 45 degree display.
gtk3 - adapted draw routine to gtk_cairo_should_draw_window. gtk-criticals with undefined drag window disappeared. The gtk-criticals showed up in debian 8.
fixed initial show of names in header window. Variable names only showed up after switching between variable and data window. The reason is that the buttons of the columns are not created. This is due to interdependency between the size allocation and the button creation. I removed the need_button mechanism.
Switch the order in which scatterplot axes appear in the graphic's caption.
Hulliger Beat <beat.hulliger@fhnw.ch> Reported that scatterplots were titled 'x vs. y'
where x and y were opposite to what is conventional. This change fixes that.

Otherwise "make distcheck" will have to regenerate it, which means
that it will have to regenerate doc/pspp.xml (because it depends on
help-pages-list) but that's not possible under "make distcheck"
because it makes the source directory read-only.

configure: Create "doc" directory in build directory.
Otherwise we get build failures from the autobuilder when the rule

introduced in commit 531de52e961c (PsppireDialog: New property:
help-page).
Developers probably didn't notice this problem because they probably
already had doc/ directories in their build directories due to
building PDF versions of the documentation at one time or another, or
because they do builds in the source directory.

New module to perform decimal floating point arithmetic for charts.
This change adds a small module to perform floating point arithmetic
with a decimal base, and uses it to calculate the graticule marks for
charts.
Rationale: Graticule marks want to be displayed in decimal. However
not all decimal values can be represented in a double precision
floating point binary. This approach pushes the precision loss from
the value of the mark, to the position on the chart - we don't
particularly care if a tick mark is a fraction of a pixel out of place,
but we do care if 4.0 is displayed as 3.9999999999

psppire-output-view: Fix segfault during printing.
psppire-output-view tried to make use of a special feature in the
cairo output driver that allowed the cairo_t to be omitted to avoid
actually rendering anything, for pagination purposes, but the cairo
code had changed and this feature had not been carefully maintained,
resulting in a segfault. This commit stops trying to use that
feature, since it seems like it could easily get broken again in the
future and doesn't have much benefit anyhow.

lexer: Include <unistd.h> to ensure 'read' is consistently replaced.
On some platforms, Gnulib #defines read to rpl_read. The lexer uses
an unreleated function pointer member named 'read' in struct
lex_reader_class. It doesn't really matter whether this name gets
replaced with rpl_read as long as it always happens consistently.
Adding "#include <unistd.h>" to lexer.h should ensure that.

cairo: Add .5pt gutter around table rules.
Commit d3fef25674baf4f4 (output: Add footnote support.) removed the 3-pt
gutter around table rules, instead putting a margin around cell contents.
This usually worked out fine, but for some tables in the GUI it caused the
rightmost rule in the table to disappear. This is probably some kind of
off-by-one error in table size computation or clipping. We may have to
eventually resolve that. However, this commit seems like an adequate
temporary fix: instead of fixing the off-by-one error, add a thin gutter
around the rules, so that the actual content of the rule doesn't get
clipped off.
