change SubViewportContainer stretch_shrink's type from int to float

[jinyangcruise]

Anyone know the reason stretch_shrink must be an int? I think a float can make it more useful.

I find it's hard to change the scale of a scene which is made by a bounch of Control node. The scene is a child of a CenterContainer, so it's position and size is determined only by it's parent the CenterContainer. I finally find a work around: add the scene to a SubViewport then add the SubViewport to a SubViewportContainer, then add the SubViewportContainer to the CenterContainer. Then I change the stretch_shrink of the SubViewportContainer to make the scene bigger.

stretch_shrink's type is int and must be greater than 1, this situation possibly limits it's ability. I don't know whether I used subviewport in a correct way.

What would a value smaller than one do? This is to speed up rendering by downscaling the viewport

It being an int makes sense or you'll have bad scaling factors very easily

Also it has to be greater than or equal to 1

I don't know whether I used subviewport in a correct way.

I suspect that you might not

[jinyangcruise]

Yes, you are right.

If you want your project to scale to various screen resolutions, use Godot's built-in support for multiple resolutions (stretch modes) instead of implementing scaling manually.

I should not use a viewport to scale my Wheel scene. The direct way is to add a control that has a min_size to contain my Wheel scene. Then my Wheel scene can be scaled to another value.
