multiple contexts ?

[Pierre-Yves Rivaille]

Hi,

I'm trying to use two Graphics Context to draw to the same window, but I'm
facing a problem, because I don't know how to instantiate the second
context with the right gstate so that it can draw to the window.

Is there a clean way to do this using DPS functions ?
Even if those DPS functions ain't implemented in xgps, I can try to write
those.

thanks,
