- *
- * When a GtkLabel is set to wrap, it assume and hardcoded width. To change
- * that width we have to set a size request on the label... but that's not
- * possible because we want the window to be able to shrink, so we MUST request
- * width of 1. Note that the height of a wrapping label depends on its width.
- *
- * To work around that, here is what happens:
- * 1) size-request is first called, an hardcoded small width is requested by
- *    GtkLabel, which means also a too big height. We do nothing.
- * 2) size-allocate is called with the full width available, that's the width
- *    we really want to make wrap the label. We save that width and restart a
- *    size-request/size-allocate round.
- * 3) size-request is called a 2nd time, now we can tell the pango layout its
- *    width (we can't do that in step 2 because GtkLabel::size-request recreate
- *    the layout each time). When the layout has its width, we can know the
- *    height of the label and set its requisition. The width request is set to
- *    1px to make sure the window can shrink, the layout will fill all the
- *    available width anyway.
