   As also written in a comment
   here: https://github.com/openjdk/jfx/pull/610
   I would like to propose one more convenience method which should be
   added to JavaFX:

public static Border stroke(Paint stroke, double width) {
    return new Border(new BorderStroke(stroke, BorderStrokeStyle.SOLID, null, ne
w BorderWidths(width)));

   I think it's quite common that you want to create a solid border with
   another width then the default of 1 (for every side).

   Note: This is also the last use case I think makes sense to add as a
   convenience method.
   Any other use case is likely to be so complex that it makes sense to
   use the normal existing constructors.

   Feel free to share you opinion.

   Betreff: Re: [External] : Re: Convenience factories for Border and
   The new API:
   1. `Border.of(Paint stroke)` or `Border.stroke(Paint stroke)` that does
   `new Border(new BorderStroke(Paint stroke , BorderStrokeStyle.SOLID,
   2. `Background.of((Paint fill)` or `Background.fill(Paint fill)` that
   `new Background(new BackgroundFill(Paint fill, null, null));`
   I don't mind either name choice.
