Wire thorn moves on color update

When the color updates the cable seems to move a lot more than just a color update.

Running on Bazzite (Linux) AMD.

note from discord:

It's not color update, it's flow direction change
And it happens because the Lua part sends the list of cables to the shader in flow order because flow order defines local UV coordinates, which in turn what controls the bubbles
The principled solution is to sort the overdrive grid vertices by coordinates before sending them to the shader, and add a flow direction 0/1
so then a link [<3109,398>,<3088,452>] is identical to [<3088,452>, <3109,398>] geometrically because it's always rendered as [<3109,398>,<3088,452>], but there's an inverse flag that flips its UV
But probably there's also a hacky solution similar to what is done now, just better
idk
