[gtkextra] gtk_plot_canvas_paint

[Dario]

Hi,
Does anyone knows what exactly the function gtk_plot_canvas_paint does in order
to repaint the canvas?

Since I must work with huge canvasses it costs a lot (in terms of time) to paint
it entirely. So I'm searching for a surrogate group of functions that can paint
only a restricted area of it.

Thanks in advance.
