Version 1.5, enabling you to draw with cubic curves:

* "Draw cubic" will switch from connecting your points with straight lines
(default) to connecting them with curves described by third-degree polynomials.
This will give you a better idea of what your cubic prism or lathe will look
like when rendered in POV-Ray.
Cubic curves need two extra points for definition, so the drawing of connecting
curves will always be two steps behind your points. For example, when you draw
point number 4 in Cubic mode, PointWriter will connect points 2 and 3, and when
you draw point number 5, it will connect 3 and 4 and so on.

NB: Drawing in Cubic mode is very computationally demanding and can slow
your computer down, so you might work faster by drawing in Linear mode and just
switching to Cubic for quick previews.
Whether you choose to display lines or curves on the screen makes no difference
to the output when you write the shapes to POV-Ray code.

Keyboard shortcut: "d" (lower case). Toggle between cubic and linear.

"D" (upper case) will display your Work in Back shape with cubic curves. Toggle
between cubic and linear.

* "PointWriterHelp.txt" is updated with these changes.
