Pre-release testing version of 5.2.5

[sfeam <sf...@us...>]

I have uploaded a tarball of a testing version of 5.2.5 to
the "testing" folder on SourceForge.  The source and the executable
built from it identify as 5.2.5a  (note the "a").

  https://sourceforge.net/projects/gnuplot/files/gnuplot/testing/gnuplot-5.2.5a.tar.gz

Please test build on your favorite platform and report any problems here.
If all goes well, I will prepare a new tarball for the official 5.2.5
release.

	cheers,

                 GNUPLOT Version 5.2.5 Release Notes
                ===================================

These release notes are for version 5.2 patchlevel 5 (5.2.5).
This release contains bug-fixes, a few changes back-ported from the
development version, and a few new features.  The most notable fixes are
(1) improved clipping of lines or other plot elements that would otherwise
extend beyond the edges of the plot. 
(2) in versions 5.2.0 through 5.2.4 function plots in parametric and polar
modes did not work with logscale x axis.

Please see the ChangeLog file for a complete list of changes made during the
course of development from 5.0 to 5.2.

Release Notes date: 01-October-2018


CHANGES IN 5.2.5
================

* NEW "set pm3d depthorder base" sorts pm3d quadrangles by projecting to z=0
* NEW "set jitter vertical" displaces y coordinate rather than x coordinate
* NEW array size can be determined automatically from the initializer
* CHANGE equivalent slope constraint for mcs splines at both ends of the range
* CHANGE treat imaginary values plotted from a using spec as UNDEFINED (NaN)
* CHANGE allow "reset" between plots in a multiplot layout
* CHANGE Deprecate linux and vgagl terminals (to be removed in 5.3)
* CHANGE placement of axis and tic labels in 3D projections on to xz or yz plane
* CHANGE default to ./configure --without-wx-multithreading
* FIX parametric function plots did not work with logscale x (regression in 5.2.0-4)
* FIX polar mode "set trange" was assumed to use radians, now it tracks "set angle"
* FIX clip polar grid lines and ticks to x/y range limits
* FIX clipping of plot "with lines" when axes are nonlinear (regression from 5.0)
* FIX clipping of all elements in finanacebars/candlesticks/boxplots
* FIX clipping of 3D splot "with labels"
* FIX strange interaction of "noautoscale" with blank data lines
* FIX alignment of boxed text to center for eps/cairolatex
* FIX incompatibility of "pm3d depthorder" and rgb color taken from data column
* FIX aqua terminal font changes in enhanced text mode
