Currently, as the user drags the caret on iOS, SuperEditor and SuperTextField snap the caret to the nearest legal caret position. While this is a reasonable behavior, it's not how iOS behaves.

The current (wrong) SuperEditor behavior:

On iOS, dragging the caret moves the caret by the exact drag amount in the current line of text, regardless of whether that x-offset is a legal caret position or not. When the user releases, the caret animates to the nearest legal position.
