The lua option is there to enable the TikZ terminal, so install its
LaTeX style files to make use of it.
Replace and deprecate old "set loadpath" command means the list of font
paths is gone.
Highlights:
* Support for 64-bit integer arithmetic
o All evaluation of expressions and functions uses 64-bit arithmetic
if supported by the hardware platform.
o Integer overflow is detected and handled according to user preference.
* Voxel grids
o Gnuplot now supports operations based on 3D grids of voxel data.
o The current content of one or more voxel grids can be referenced by
splot commands to assign colors or other properties to plot elements.
o Data in a voxel grids can be plotted by splot styles dots, points,
or isosurface.
* Pixmaps as objects
o "set pixmap" allows import of a png/jpeg/gif image as a pixmap that
can be positioned anywhere in a plot or on the page. Unlike plotting
"with image", pixmap objects retain their original aspect ratio and
size independent of axis scaling or rotation.
Example: http://gnuplot.info/demo_5.4/pixmap.html
* New plot styles and plot options
o 3D plot style "with polygons" reads polygon faces from a data file.
These can be used to create a surface or to describe a solid object.
Example: http://gnuplot.info/demo_5.4/polygons.html
o "splot $voxelgrid with isosurface" creates a tessellated 3D surface
enclosing voxels above a requested threshold level.
Example: http://gnuplot.info/demo_5.4/isosurface.html
o "set spiderplot" selects a new plotting mode for creating spider
plots, also known as radar charts. These are essentially parallel
axis plots in which the axes are arranged radially rather than
vertically.
Example: http://gnuplot.info/demo_5.4/spiderplot.html
o Plot styles "with circles" and "with boxes" can be used in 3D plots.
Example: http://gnuplot.info/demo_5.4/3Dboxes.html
o 2D plot style "with arrows" is a variant of "with vectors" in which
each arrow is specified by x:y:length:angle rather than x:y:dx:dy.
o pm3d surfaces can have individual fill styles and separate top/bottom
fill colors.
Example: http://gnuplot.info/demo_5.4/hidden_compare.html
o pm3d option "noclipcb" causes quadrangles with palette color outside
cbrange to be omitted from the plot rather than being assigned a
color clipped to cbmin or cbmax.
o Contour line types can be customized.
Example: http://gnuplot.info/demo_5.4/custom_contours.html

Release 5.2.1
A few bug-fixes present in the distributed package for 5.2.1 are not yet
commited upstream because the repository is in the process of migration
from cvs to git.
* src/graphics.c (plot_betweencurves):
plot 'foo' with filledcurves below y=bar
would fail to identify "below" regions where the y value foo[x] at the
start or end of the region was exactly equal to bar.
* src/axis.c (gen_tics): `set log x; set xtics foo` would always place
the first axis tic at foo rather than at (foo / base^N) for suitable N.
* src/win/winmain.c (ConsolePutS, ConsolePutCh): Use standard file IO
instead of Console API to enable word-wrapping on Windows 10 and to
allow for redirection of stdout/stderr.
* term/post.trm: Raise the limit on number of relative moves before
a "stroke" so that a full circle as drawn by do_arc() does not glitch
due to insertion of a "stroke xx yy M" sequence that resets the
dot/dash pattern.
* src/plot2d.c (eval_plots): If the range for logscaled y axis is empty,
e.g. the plot holds a single point, auto-extend the range rather than
giving up with an error.
