Double click signal for Button?

[feois]

Make a signal like Button.pressed() but for double click. I know it can be done through _input() and double_click but a signal can be a better enhancement

What's the use-case of a button that needs to be double-clicked? How common is it?

[feois]

Basically if single click then effect A, if double click then depending on the situation, either just effect B or effect A + B. If you want use case, something like a skill button that when clicked trigger skill effect but also trigger extra effects when double clicked under certain circumstances? I guess it might not be too common.

How would this handle the new signal? If the pressed signal is not called for double clicks by default this breaks compatibility

[feois]

A new property that determine pressed is emitted or not with default being yes since backward compatibility

For people finding this: you can get InputEventMouseButton in _gui_input or the gui_event signal. That way you know the the interaction is on your Control (unlike with _input). And, of course, you can read the double_click property. Bonus: Since it is not a Button thing, you can implement double click on other controls (e.g. a Label or a TextEdit).
