Godot - Customizing Label Text Shadows

This is a code example for customizing Label text in GDScript.

You can customize the shadow color of Label text by specifying the `font_shadow_color` property with `add_theme_color_override()`.
You can change the shadow position with `shadow_offset_x` and `shadow_offset_y`, and the shadow size with `shadow_outline_size` using `add_theme_constant_override()`.

var label = Label.new()
add_child(label)

# Shadow color
label.add_theme_color_override("font_shadow_color", Color("#FF2222", 1))
# Shadow position
label.add_theme_constant_override("shadow_offset_x", 5)
label.add_theme_constant_override("shadow_offset_y", 5)
# Shadow size
label.add_theme_constant_override("shadow_outline_size", 5)
