Comment 13 for bug 730740

It works on more than a fixed set of applications: the whitelist is meant to enable it by default, for a set of applications that we are testing more thoroughly. It should work for all gtk applications using gtk_scrolled_window, ie most of the gnome applications we know of.

The missing LTR support is because we want to test that fully as well. It should work reasonnably with LTR languages, but not with the level of visual quality we aim for.
