Entirely rewritten credits roll for bitmap LCDs, loosely based on my Clock credits roll. Text flies in from left, a line at a time, until the LCD is full, and then each line flies out and a new line flies in, until the list of names is exhausted. Significantly improves readability on H1x0, and probably on all other models as well.
