/*
* There is a backward compatibility bug in motif 2.0 that prevents
* the XmScrolledWindow class from behaving just as the motif 1.2
* one. For whatever reasons, the mozilla scrolling code depends on
* the 1.2 behavior. Fixing the problem in Mozilla should not be
* hard. The logic in scroll.c should probably be updated to work
* with both motif 1.2 and 2.0.
*
* The current hackery solution (yes its disgusting) is to use the
* XmScrolledWindow code from 1.2. In defense of Netscape: The only
* reason whay such a sickening solution was used, was to make the
* free mozilla date with building motif 2.0 code.
