1184  * that width we have to set a size request on the label... but that's not
1185  * possible because we want the window to be able to shrink, so we MUST request
1186  * width of 1. Note that the height of a wrapping label depends on its width.
1187  *
1188  * To work around that, here is what happens:
1189  * 1) size-request is first called, an hardcoded small width is requested by
1190  *    GtkLabel, which means also a too big height. We do nothing.
1191  * 2) size-allocate is called with the full width available, that's the width
1192  *    we really want to make wrap the label. We save that width and restart a
1193  *    size-request/size-allocate round.
1194  * 3) size-request is called a 2nd time, now we can tell the pango layout its
1195  *    width (we can't do that in step 2 because GtkLabel::size-request recreate
1196  *    the layout each time). When the layout has its width, we can know the
1197  *    height of the label and set its requisition. The width request is set to
1198  *    1px to make sure the window can shrink, the layout will fill all the
1199  *    available width anyway.
