/*
|
||||
* @@@ 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.
