Remove the requirement for the number of frames to be an exact multiple of the frames visible

[janthonyeconomist]

Problem:
If there is 4 frames visible, and 9 frames, then the system will only allow you to scroll once and the last frame is alway hidden.

Solution:
Always allow the person to scroll to the very end, but only scroll to the offset that doesn't display empty space.

Looks like you also need this:
