Well first of all, the MOTIF version I have requires its own
version of Xt called Xtm.  MAJOR bummer.  However, I have been
informed that there is a version of MOTIF that uses normal Xt.
This being the case, you CAN put Athena widgets inside of MOTIF
widgets and vice-versa, however, they won't always act like you
want them to.

IE You could never get a MOTIF toggle widget to align in anything
other than one of the MOTIF layout managers.

Layout managers should *NEVER* check the classes of its
children or should the child widget check the class of its
parent. This makes your widget very unfriendly and
non-portable (sometimes).
