This can't be done at all using just ScrollWindow(), I'm afraid. To be
honest, I'm not sure how should scrolling be implemented efficiently
nowadays, i.e. whether it's actually still important to scroll the existing
window contents or if it's better to just refresh it entirely. I suspect it
could well be the latter and wx scrolling model (based on the APIs dating
from 40 years ago) is not appropriate at all any more...
