Add a square fill mode to GradientTexture2D

[MewPurPur]

Implements godotengine/godot-proposals#6712 (I moved the demonstrations and use cases there)

This is an example of what it does what it used to look like (see comments for a more recent version):

Feel free to discuss about better implementations, also if you think the feature isn't needed.

Production edit: Closes godotengine/godot-proposals#6712.

Heh, I was planning on implementing this at some point 🙂

I suggest opening a proposal to discuss use cases. I can think of a few:

• Create a blob shadow texture for square-shaped objects. I already use GradientTexture2D for blob shadows in demo projects.
• Create grid textures (useful for prototyping). See also Display a checkerboard pattern on the fallback 3D material godot-proposals#6138.

Sure thing, I opened a proposal. godotengine/godot-proposals#6712

I don't think this can be used for checkerboards.

I don't think this can be used for checkerboards.

Indeed, this can only be used to draw grids. Still, this may come in handy for prototype textures when you don't want to reach out for https://godotengine.org/asset-library/asset/780.

Changed it up, the new implementation forces it to be a square, making it more alike radial textures (it can still be a rectangle if you resize the texture)

Tested locally (rebased against latest master 06ccbfe), it works.

Seems tiny, useful, and tested 👍

Thanks!
