That'd be my question.  Depending on the size of the text, you may
wish to blit the entire string first, and then scroll that bitmap.
Or break it into words, and then blit them each individually.
e.g.:

  No good deed goes unpunished.

You could break that up into:
  No
  good
  deed
  goes
  unpunished.

And then, at various points during the animation, you'd be
blitting:

   |        N|o

   |     No g|ood

   |  No good|

   | good dee|d

goo|d deed go|es

 de|ed goes u|npunished

   | unpunish|ed

unp|unished  |
