Speeding up Simple Canvas Loop

[Randall Hopper]

    create_line = canvas.create_line
    for line in lines:
      create_line( line, width=0 )

Can canvas items for Tkinter canvases be created by a C extension (these
vertices are actually coming from C code)?

The performance of this GUI app is acceptable except for the above loop,
and it alone can literally take minutes (400-30k iterations).

Thanks,

Randall
