Obsolete object constructions

The following object construction macros are made obsolete by the enriched <object> format:
\begin{defs} Version 2 object\hfil & Replacement \cr \noalign{\nobreak\smallsk... ...c \cr & \vert\object+=<\vert<dimen>\vert>{\vert<text>\vert}\vert \cr \end{defs}
where rotation is done in a slightly different manner in version  (it was never accurate in version 2).

2 These are mostly just the unmodified version 2.6 code:

We also reimplement the version 2 undocumented ??c![] quarter circle which is now called |@@| of the frame extension.
