Great! With the latest update of libnsfb/src/surface/plan9.c my drawing 
performance is now back to how it was before. I didn't notice before 
that it was scrolling that triggered p9copy(), but the window now 
redraws much nicer when scrolling :-)

Kenji, you might not see a speed up if you run the browser on your 
terminal or all-in-one plan9 installation, but if you run it on a 
cpu-server it makes a difference depending on the bandwidth.

I still might continue to implement compression of big updates and 
upload them with cloadimage() instead of loadimage() - especially if the 
framebuffer version of netsurf will stick around for some while.
