Change the y-axis direction for a 2d Cider gnuplot. The device surface is at the top and downwards is into the material, which is the normal presentation. Note that the x/y mesh commands in a Cider model also affect the orientation.

Add parameter 'isgrid' to plotting of arcs.
Smithgrid and polar plots could not discern between xgridwidth and
xbrushwidth. This is now available, similar to straight line plotting.

Add code in graf.c to merge connected lines with the same slope before
plotting. This speeds output and reduces file size when the vector
length is much larger than the number of pixels. It should help with
Feature Request #58 :
"Graph plotting under windows redraw very slow and hard to work with",
but is not a full fix.

The re-painting due to mouse-click under MS Windows is caused by line 561
of windisp.c. Upon left mouse button up the plot recangle is invalidated,
and a WM_PAINT message is generated (same on line 614 for right mouse
button up). If not re-pained, artifacts may be left on the canvas after
collecting coordinate data.
Shifting the command InvalidateRect to a place where it becomes active
only after the mouse has been moved, does the trick. Simple clicking
(right or left) will not cause a re-paint any more.

The AD and DA hybrid XSPICE bridges consume a lot of
memory (one state per time step added). Memory of
previous time steps is not recovered.
