function NewRichEdit( AParent: PControl; Options: TEditOptions ): PControl;
Creates rich text edit control. A rich edit control is a window in which the user can enter and edit text. The text can be assigned character and paragraph formatting, and can include embedded OLE objects. Rich edit controls provide a programming interface for formatting text. However, an application must implement any user interface components necessary to make formatting operations available to the user.
Note: eoPassword, eoMultiline options have no effect for RichEdit control. Some operations are supersided with special versions of those, created especially for RichEdit, but in some cases it is necessary to use another properties and methods, specially designed for RichEdit (see methods and properties, which names are starting from RE_...).
Following properties, methods, events are special for edit controls:

function NewRichEdit1( AParent: PControl; Options: TEditOptions ): PControl;
Like NewRichEdit, but to work with older RichEdit control version 1.0 (window class 'RichEdit' forced to use instead of 'RichEdit20A', even if library RICHED20.DLL found and loaded successfully). One more difference - OleInit is not called, so the most of OLE capabilities of RichEdit could not working.
