In this case, the setCaretTo parameter will be set to a value other than Integer.MIN_VALUE, and will represent the relative pixel column (to the editor) where the mouse was clicked. Using this, it will preserve the mouse scroll (so that the left-edge character will be referenced by EditorConfig.scrollX) and the cursor X will be adjusted to represent the clicked character.
