TXFALayoutEngine.Create

單元：HPDFXFALayout

constructor Create(ADoc: TXFADocument; APageW, APageH: Double;
  AWarnings: TStringList; AMeasureText: TXFAMeasureTextFunc = nil;
  AResolveText: TXFAResolveLayoutTextFunc = nil; AMaxFieldItems: Integer = 0;
  AMaxLayoutOperations: Integer = 200000;
  AResolveProperty: TXFAResolveInstanceProperty = nil;
  AResolveScope: TXFAResolveInstanceScope = nil);

尾端的選用 resolver 加入每實例屬性與 repeat-parent 繫結，傳 nil 則維持既有呼叫端行為；layout engine 依然不依賴 HPDFDoc

繫結與選擇器規則、支援的事件語法、預算預設值、交易式發布、持久化、繪製與相容性邊界，見 Dynamic XFA Instance Presentation
