IMPLEMENTATION:
- Why does 'nrformats' leak from the popup window buffer???
- - Option to set first line to display (useful for a preview window)
- Disable commands, feedkeys(), CTRL-W, etc. in a popup window.
Use NOT_IN_POPUP_WINDOW for more commands.
- Add 'balloonpopup': instead of showing text, let the callback open a popup

minwidth Minimum width of the contents, excluding border and

hidden When TRUE the popup exists but is not displayed; use
`popup_show()` to unhide it.
