box-flex-group too.  You can fake this with flex units, if necessary,
by just setting very large flex values on some elements, and ordinary
flex values on other elements.

.one { width: 1000000fl; } .two { width: 1fl; }

should act virtually identical to:

.one { box-flex: 1; box-flex-group: 1; } .two { box-flex: 1;
box-flex-group: 2; }

Is this commonly used in XUL things?  If so, are more than two levels
commonly used?  If it's very rare to use more than two levels, I think
I'd be fine with the "very large flex" hack, but not if it was somehow
common for there to be 3 or more groups.
