/* bgo#315462 - For single-line labels, *do* align the requisition with
* respect to the allocation, even if we are under-allocated. For multi-line
* labels, always show the top of the text when they are under-allocated. The
* rationale is this:
*
* - Single-line labels appear in GtkButtons, and it is very easy to get them
* to be smaller than their requisition. The button may clip the label, but
* the label will still be able to show most of itself and the focus
* rectangle. Also, it is fairly easy to read a single line of clipped text.
*
* - Multi-line labels should not be clipped to showing "something in the
* middle". You want to read the first line, at least, to get some context.
