all widgets, has been effected. Sorry, there was no getting around this
one. Pretty much all widgets have slightly changed, because pretty much all
widgets previously behaved slightly differently:
* `ncselector` no longer accepts `y, x` placement parameters.
* `ncselector` now takes ownership of the provided `ncplane`. It is
destroyed by `ncselector_destroy`/`ncselector_create`.
* `ncmultiselector` no longer accepts `y, x` placement parameters.
* `ncmultiselector` now takes ownership of the provided `ncplane`. It is
destroyed by `ncmultiselector_destroy`/`ncmultiselector_create`.
* `ncselector_create()` and `ncmultiselector_create()` now take ownership
of the provided `ncplane`. On an error in these functions, the `ncplane`
will be destroyed. Otherwise, the `ncplane` is destroyed by
`ncselector_destroy()` or `ncmultiselector_destroy()`.
* `ncselector_create()` and `ncmultiselector_create()` no longer accept
`int y, int x` placement parameters. Just place the `ncplane`.
* `ncselector_options` and `ncmultiselector_options` have lost their
`bgchannels` members. Just set the base character for the `ncplane`.
* ...
