profile: ignore animation-speed setting when printing

When printing, the animation speed was set to 0 by the
caller and later reset to the original value. Instead of
modifying global state, set it internally (in the profile-code)
to zero when in print mode.

This is another small step in making the printing independent
from the shown profile.
