Add a DisplayServer method that provides info about rounded display corners

[Absotively]

Describe the project you are working on

A solitaire card game for Android

Describe the problem or limitation you are having in your project

I am displaying the score in one corner of the display and a timer in another corner. On a display with rounded corners these are clipped by the rounded corners. I would like to shift these horizontally only on displays with rounded corners, and only enough to prevent clipping. Without information about the current display's corners, I can't do this.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

A DisplayServer method that provides info about rounded display corners would let me adjust my game's layout to prevent clipping by rounded corners.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

$ScoreLabel.position.x = DisplayServer.get_display_corner_radius(DisplayServer.CORNER_TOP_LEFT)

(This is influenced by having just skimmed relevant Android documentation, I am not in any way attached to this specific design.)

If this enhancement will not be used often, can it be worked around with a few lines of script?

No. I've been unable to find any way to access information about rounded display corners from script.

Is there a reason why this should be core and not an add-on in the asset library?

• It would be useful on both Android and iOS.
• DisplayServer.get_display_cutouts() exists, so presumably DisplayServer is the proper place for detail about the display shape.

Other

• iOS corner shape is apparently more complicated; I don't have any good ideas about if or how this feature should account for that.
• Add (root) window's "safe area" method that works regardless of window position, device, screen ID, notch, rounded corners, etc #11106 suggests a way that Godot could provide one-size-fits-all layout adjustments that account for rounded corners. However, it would not be flexible enough for my use case; I want to adjust only elements that are near corners, and I want to adjust them in a specific direction that I control.
