Useful for `Light2D` nodes. It's quite cumbersome to create radial gradient textures to be actually useful for `Light2D` nodes by default quickly enough. Based on `GradientTexture2D`.
Mostly useful for light textures, but also allows for higher color interpolation accuracy for RGBA8 images.

Useful for
Light2Dnodes. It's quite cumbersome to create radial gradient textures to be actually useful forLight2Dnodes by default quickly enough, so most of the time it wouldn't be intuitive for beginners, so this should help to speed up the workflow in general.Based on
GradientTexture2D.This PR also increases default texture size to 256x256 pixels, see rationale in godotengine/godot#47410 (comment).
Note for Godot 4.0: auto-instantiation of
Gradientwill have to be done via editor as suggested in godotengine/godot#39479, otherwise there are known limitations of reverting the property to default value.
