We are going to need a way to get the currently used instead of
requested space for a cell renderer anyway to fix some bugs.  I am still
contemplating if that is worth using one of the class padding pointers
or whether I can find another way to do it.

Last time I used Windows it didn't put some popup window over the tree
view row.  But rather, as you said in the bug report, for example Windows
Explorer displays the name in the left pane; which is IMHO a much nicer
way of solving this problem.  Also, I feel that different applications
need a different solution for this problem.  Personally, I think that
"inplace hints" is too specific to put in GtkTreeView.

As I said above I personally don't think this belongs in GTK+.  Of
course this does not have to be a permanent no, we can always revisit
the issue once it's "proven" and more apps are using it to solve the
same problem.

In my experience getting patches like this in always takes some time and
does not happen within a few days.  For now it seems like a good idea to
hold off, leave it in bugzilla for a while, have it mature and see
whether the app developers see a good use for this feature.
