"Smooth Scrolling" has been implemented(!). Now scrolling is as fast as 
in text mode wscons. A new benchmark result:

$ time ls -l /usr/bin
real 0m1.153s
user 0m0.102s
sys  0m0.787s

It can be faster if i386 specific optimization is used (at the cost of
portability, though). Has anybody tried this on non-x86 platform which 
has VGA compatible display hardware?
