I'd like to at least start discussion on text-overflow improvements,
because we've found that we want to use it (and thus want to implement
it) in Webkit components, but the current version in UI3 is too weak.

Here are some use-cases we've run into that we think can be solved by
something like the older version of text-overflow that was in Text:

1. Hiding a timeline label entirely when the video control shrinks
small enough to make it start overflowing.  It looks like this could
have been achieved with "text-overflow: ellipsis-word '';", and
wrapping the label in a <span style="display:inline-block;"></span> if
it was multi-word (which it may be once internationalized).

2. Eliding the middle of a long url or filepath when it starts to
overflow, keeping the important bits at either end visible as long as
possible.  I don't think this was achievable in the old Text draft,
but it's apparently very useful in application frameworks that provide
this functionality.  Some provide a smarter version specialized for
urls/filepaths, where it additionally tries to preserve content after
the last / as long as possible.

3. Providing a UI where several small sections have a max-height set
and may or may not overflow.  If they do overflow, you want to
indicate that there's more content "below the fold", so users know to
click on the header or whatever to go the page showing the whole
thing.  This was doable in the old Text version by providing a second
string to text-overflow-ellipsis.
