Comment 7 for bug 330271

inkscape currently renders tiles of the image.
1.) this can be distributed to the different cores.
2.) also inkscape can render in two passes; first with lower accuracy and the second having the full accuracy. To get a full repaint quickly.
3) Inkscape should respond to user input after drawing a single tile

points 1) and 2) are to be implemented.
I have no glue about 3)

my 2 ct.
