Set the color tables and linewidths personal for each graph,
added to strucht graph
Use only these data for plotting.
If zooming a plot windows, set as an extra parameter the graph id
of the 'mother graph'. Copy its color and line data to the new graph.
This is done by an extra parameter sgraphid to the internal plot
command that is issued in fcn PlotWindowProc().
Thus zooming will keep the background, text/line and graph colors.
Function setcolor() will always look into the colorarray of the
current graph.

enable color and font selection for X11:
Add graphics context gridgc for plotting the grids.
Enable rgbd:, input of color by RGB 0 ... 255
If no color1 (text/grid) is given,
select black or white according to backgrund color.
Error message, but no crash if font cannot be selected.
Enable separate linewidth selection for grid and graph.

plotting/grid.c, bug fix, avoid string buffer overflow
Prevent a crash of example/FFT_test.cir.
Buffer 'buf' in function drawlingrid() has been too small.
Increase 'buf' size, and add some protection.
The example file examples/plot/test-small-plot.cir
shows the limits of plotting:
difference in two numbers at digit 14 is plotted well.
at digit 15 is plotted with bugs.
at digit 16 is reduced to integer.
consider compiling with
-O1 -D_FORTIFY_SOURCE=2
for gcc, and
/GS
for visual studio.
