#windowkill

Before, I just had each window hooked up to its own camera in the scene that it'd follow but there were two problems with this:

Their zoom factors were inconsistent as you resized the window which looked weird and also I wanted the "dpi" to remain consistent and the world to look static no matter the window size

Now, I don't know exactly how Godot's rendering pipeline works, but I have a feeling that each of those cameras were individually rendering the scene which would waste a *lot* of resources. probably not an unplayable amount but it still irked me when so much of it would be redundant.

So I swapped to a setup of having two sub viewports, one that contained what would be the game world and one that just contained a TextureRect that held the image of the first subviewport.

And then each window has its own TextureRect that samples that image with a script that drives some shader values to crop it based on window size and position. The formula for this ended up being a lot simpler than I thought haha but I'm kind of bad with math problems like this

(where mx and my are monitor size values)

There's prob some better way to do this where I don't have to send data between the CPU and GPU but I'm fine with it for now and I don't think it'll make a huge difference.
