+ * @@@ The idea is to get input to trigger hovering over the pop-up.
+ * However, this doesn't work because the overlay has not been drawn
+ * yet and therefore has not created its AoI. We therefore only get a
+ * chance to begin hovering at the next motion update, which may
+ * already be outside the pop-up.
+ * Probably the only way to fix this is by making overlay_add do the
+ * layout calculation and create the AoI immediately.
+ * Another problem occurs as deep zoom levels, when the label is larger
+ * than the pop-up. Then we can trigger pop-up creation from a location
+ * that will be outside the pop-up.
+ * We could fix this by aligning the pop-up with the mouse position
+ * instead the box, either in general, or in this specific case. Not
+ * sure if it's worth the trouble, though.
+ * Both issues result in a "hanging" pop-up because AoI (and input)
+ * don't even know we're hovering. The pop-up can be cleared by
+ * - hovering into it,
+ * - hovering over some other glabel, or
+ * - clicking.
