Implementing asychronous loading of regions of data for a smoother panning experience

[Syntaf]

The current pan feature is clunky and messy, moving about the plot is painful and takes a large amount of time to load larger sections of data.

A good feature to have would be for the program to asynchronously load an additional set of data, both on the right and left of the view. When the user decides to pan left or right, this preloaded data would be used for panning while a new section would be preloaded for a smoothing viewing experience. If the user began scrolling too fast, it would simply hang on waiting for the asynchronous operation to finish before allowing the user to continue scrolling.
