For that matter, I'm not quite sure why we have separate nsHTMLContainerFrame
and nsContainerFrame, but that's also fodder for a separate bug.

dbaron, roc, is there a point to having these be separate classes?

I don't think so.

There was one issue - both nsHTMLContainerFrame, nsContainerFrame
implements BuildDisplayList.  Identically, except nsHTMLContainerFrame
uses DISPLAY_CHILD_INLINE and nsContainerFrame does not.

Investigating all classes that inherit nsHTMLContainerFrame...
implements BuildDisplayList that explicitly calls nsHTMLContainerFrame::BuildDisplayList
does not implement BuildDisplayList

I made the above four have a BuildDisplayList that calls a new (protected)
convenience method BuildDisplayListForInline that implements the

The remaining derived classes all implements BuildDisplayList but
does not call nsHTMLContainerFrame::BuildDisplayList.
