Glyph CSS Styling Limitations

Glyph CSS styling does not seem to work.

In particular:

1. -fx-text-fill: red; // works
2. -fx-stroke:blue; // is ignored
3. -fx-font-size: 48; // corrupts icon

public class GlyphCSSTest extends Application {

@Override
public void start(Stage primaryStage) {

Glyph glyph1 = new Glyph("FontAwesome", FontAwesome.Glyph.BEER);
glyph1.setFontSize(48); // programatically set font size works
glyph1.setColor(Color.RED); // programatically set color works

Glyph glyph2 = new Glyph("FontAwesome", FontAwesome.Glyph.BEER);
glyph2.setStyle("-fx-text-fill: red; -fx-background-color: green;"); // Works as expected

Glyph glyph3 = new Glyph("FontAwesome", FontAwesome.Glyph.BEER);
glyph3.setStyle("-fx-text-fill: red; -fx-stroke:blue;"); // -fx-stroke ignored

Glyph glyph4 = new Glyph("FontAwesome", FontAwesome.Glyph.BEER);
glyph4.setStyle("-fx-text-fill: red; -fx-font-size: 48;"); // -fx-font-size: 48 corrupts icon

HBox root = new HBox();
root.setSpacing(10);
root.getChildren().addAll(glyph1, glyph2, glyph3, glyph4);

primaryStage.setTitle("Glyph CSS Test");
primaryStage.setScene(new Scene(root, 160, 70));
primaryStage.show();
}

public static void main(String[] args) {
launch(args);
}

}
```

Start by running the provided GlyphCSSTest SSCCE and inspect the Glyph styling and font-size handling, along with the FontAwesome glyph setup. Compare the CSS cases with the programmatic setters; done means the reported stroke and font-size behaviors are understood and corrected without corrupting the icon.
