The following methods in Scene were former `impl_*` method that were intended
to be encapsulated as part of
[JDK-8157295](https://bugs.openjdk.java.net/browse/JDK-8157295) in JDK 9, but
were mistakenly left as public:
public void disposePeer()
public void enableInputMethodEvents(boolean enable)
public void processKeyEvent(KeyEvent e)
In the fix for [JDK-8157295](https://bugs.openjdk.java.net/browse/JDK-8157295),
the `impl_` prefix was removed, and the necessary accessors were added, but the
`public` modifier was not removed. See the diffs for these three methods in
Scene.java:
[`disposePeer`](https://github.com/openjdk/jfx/commit/d864a620dfc7631585872547b42dcf93e9d570e6#diff-72cb5f9e4cc8a3804417166fdef390361e82d5890603f4e5158c9fc70c22e9daL833),
[`enableInputMethodEvents`](https://github.com/openjdk/jfx/commit/d864a620dfc7631585872547b42dcf93e9d570e6#diff-72cb5f9e4cc8a3804417166fdef390361e82d5890603f4e5158c9fc70c22e9daL2221),
[`processKeyEvent`](https://github.com/openjdk/jfx/commit/d864a620dfc7631585872547b42dcf93e9d570e6#diff-72cb5f9e4cc8a3804417166fdef390361e82d5890603f4e5158c9fc70c22e9daL2129)
We will deprecate these methods for removal with the intention to remove them
from the public API in a future version of JavaFX. This will need a CSR.
NOTE: this is targeted to `jfx17`.
