Ping Pong buffers

[Absulit]

• a way to swap two existing buffers of the same type

Ideas:

// same type, will throw error if not
points.swap('bufferA', 'bufferB')

// this because binding textures already are two textures in one
points.swapBinding('name')

Current implementation has turned out to be quite complicated because I create 3 sets of entries, each one possible different to match needs of the compute, vertex and fragment shaders, so each time I create the entries, I create a copy of them to swap the buffer references, but I think part of the issue is that I'm iterating over the #storageItems (list of the initial info when a Storage buffer is created), so I add a flag to the storage item and to the other storageItem that I should swap, like in this initial setup

// code from setStorageSwap()
storageInput.pingPong = {
    swapTo: storageOutput,
};
storageInput.indexUpdated = false;
storageOutput.pingPong = {
    swapTo: storageInput,
};
storageOutput.indexUpdated = false;

this.#pingPongEnabled = true;

but after I swap the first set of entries, the indexUpdated flags are now true, so in the next creation of entries for the next shaders, they are not swap. I think that's the issue but I just tried again based on this assumption and didn't work, so I think I need to forget about this for a while.

I will keep the branch, but I will not use it anymore, I would prefer to erase everything than step on past mistakes.

For now I think to accomplish the needs of a ping pong buffer, it would be better to stick to arrays and swapping indices, or using a Binding Texture which I think serves the same purpose.
