Added UI cursor configuration to chrome metric

[Mailaender]

This allows different cursors in menus and in-game.

[pchote]

Did you consider defining these on ViewportControllerWidget? We are already defining a bunch of ingame cursor types there, so it would be a much better fit than the chrome metrics (that we should be aiming to remove, not expand!).

[Mailaender]

Yes, I tried a few things to keep this isolated to mod code only with custom button widgets which breaks as soon as I hit scroll panels which inherit the default button and also all UI configuration have to be forked. Changing the default and hacking view port controller and world interaction widget failed for me as those don't control all the cursors, they return null only for the IOrderGenerator to override them. Finally, I went with this which is minimally invasive and removes some hardcoding which probably is always good. ViewportControllerWidget is probably not available in Game.cs.

[pchote]

Can you please also squash the fixups after addressing that last issue?

[pchote]

The latest version appears to have reverted the earlier changes to remove WidgetDefaultCursor.

[Mailaender]

You specifically asked for it in #18458 (comment)

[pchote]

No, that example has WorldDefaultCursor, but specifically asked to remove WidgetDefaultCursor, which I then elaborated on further in #18458 (comment). You did that in the previous round of commits, but appear to have undone those changes possibly by force-pushing changes made on a stale local branch?

[Mailaender]

Ah now I see. Got confused there. Should be fixed now.

Lgtm otherwise.
