Shrinking the image would require ImageMagick that is not always available.
But I think not showing the image would be better, and this is already possible
by calling the fancy function with the argument `concise' equal to t.

When I run Emacs with `-geometry 80x42' then the final *five* lines
are not visible.  The calculations are wrong because they can't account
for variable-height fonts used on the splash screen.
