戻り値
Returns True when a complete element or verified placed fragment was drawn
使用上の注意
- A split must provide both a placed element and an overflow element
- The placed fragment is measured again and must fit before Draw is called
- The returned THPDFLayoutOverflow owns its continuation until DetachElement is called
