Visual shader ports are expandable by default for vector types

Addresses godotengine/godot-proposals#6182 (comment)

Works as expected:

Are we sure we want red green blue? we take in x y z? they are the same sure, but why not name them r(x) g(y) b(z) or red(x) green(y), something like that? :)

[QbieShay]

I think that could be done in a future PR, this just uses the default implementation

People tested the changes and the code is decent

Looks good, however these expand buttons (which are toggleable, but do nothing) shouldn't be there, should they?

The ColorConstant node on the right does not have them.

Edit: Also I just noticed in @paddy-exe's screenshot that there seems to be some weird thing happening with the component ports of Vector3Parameter (also reproducible with Vector2/4Parameter):

[QbieShay]

that's really strange, it shouldnt show for them

[Chaosus]

Ah, as far as I remember I did not make this change in original PR, cuz I did not manage it to work correctly with nodes with multiple vector ports.

The code for _add_node in VisualShaderEditor need to be fixed to make it work properly.

[YuriSizov]

So despite the two approvals, this still needs some work, correct?

[QbieShay]

Yeah i haven't gotten back to this yet. Anybody that wants to pick up this work is welcome, i won't have time for a bit.

Stale review

Hey there, I'd like to pick up this PR, if still possible :)

[QbieShay]

Sure go ahead! I haven't had the energy to continue on this so that'd be very welcome 👍

[DennisManaa]

Hey again, just would like to mention the new PR, where I finished the work on this issue :)
