Sizing ScrollBar components

Scroll bars added to text fields are automatically sized to fit the text field. If you resize the text field, the easiest way to resize a scroll bar instance is to drag it off the text field and then back on again. You should not use the `FScrollBar.setSize` method to size scroll bars attached to text fields.

Advanced users and programmers using the ScrollBar component to add scroll bars to movie elements other than text fields can size scroll bar instances using the Free Transform tool during authoring, or using the`FScrollBar.setSize` method at runtime.
