image preview starts over if larger than 240 columns

[MartinNohr]

When the option to preview while displaying on the LED's hits the 240th column the display starts over on the 1st column. It might be a nice option to allow it to scroll instead.

For neatness, yes it would be more logical for the image to scroll. I normally use the countdown time bar, but decided to use the preview option to see if it helps in my timing. I find the visual aloows me to time/walk much better seeing the image scan across the screen. So, for my longer patterns it would be ideal for the image to scroll across instead of wrapping around to start.
