Gnuplot core
- CLIP lines & points

- pm3d - smooth shading
Obscure ideas
set decimalsign ','

High priority
- fix the syntax for

Notes
Hans's note
Once we have lua in place it should not be that difficult to make a mechanism that works as follows:
- context calls gnuplot and opens a socket
- and starts waiting for gp to finish
- when gnuplot needs dimensions it talks back via the socket
- tex executes the command send by the socket
- etc
it needs some thinking but i think that it is possible
closed curves in parametric plots
- it's probably not seen that easy, but if you want a circle with --cycle, set trange [0:2*pi]
