Will this library include the possibility of clipping? It is one reason why
in Plotchart I rely heavily on raising and lowering canvas objects.
A window-less plotting facility sounds like an interesting alternative.

Hello,
Yes, clipping is already supported in tclmcairo 0.2.
Demo 13 has just been added to show this and
and a cheat sheet in the docs to go with it.

The library has been renamed. tclmcairo

regards,
Gregor
