based on individual view dimensions and add label to size
control.
(BWindow_set_min_size): Delete function.

handle_one_xevent.
* src/xfns.c (x_hide_tip): Remove "bloodcurdling hack".
* src/xterm.c (handle_one_xevent): Add a better version here
instead. The code is unlikely to be hit as well, since tooltip
frames are typically deleted, not just hidden.

`flush_frame'. (bug#55193)
