RFR: 8295078: TextField blurry when inside an TitledPane -> AnchorPane [v3]

[Marius Hanl]

> The problem here is, that the `AnchorPane` does not use its snapped insets.
> Therefore, the fix is to replace all `getInsets().getXXX` calls with their corresponding `snappedXXXInset()` methods.
> 
> Note: The reason the `AnchorPane` inside  a `TitledPane` is blurry in the first place is because a `TitledPane` applies padding to its content.
> Line 2995 in `modena.css`:
> 
> .titled-pane > .content > AnchorPane {
>     -fx-padding: 0.8em;
> }
> 
> which translates to 9.6px.
> 
> EDIT: This is btw a good example of the JUnit 5 feature `@ParameterizedTest` with `@ValueSource`
