/* This is the way we have to make changes in the document when the slider moves.
* What we should be able to do: Range.Text = PatchSelection.selection
* What we have to do instead:
* Collapse the patch's range to the beginning of the range
* Add the new text after this 0-length range. The range now extends to contain this new text.
* Collapse the range to it's end. This puts a 0-length range between the new text and the old text to be deleted.
* Delete the next n characters, where n is the length of the old text. i.e. delete the old text.
* Move the starting point of the range to the beginning of the new text. Now the range reflects the location of the new text.
*
* Why do we have to do this? Ranges behave weirdly when you add/remove text at the point where ranges touch.
* By doing this convoluted process, we ensure that we never add/remove text in a way that causes ranges to overlap.
