GPU-accelerated cellular automata template in Godot.
Uses GLSL3, but it should be possible to run it on GLSL2 with minor tweaks.
Scroll wheel = select material
Click = place material
Enter = pause/play
Space = step once
The current state of the simulation is stored in a texture, rendered in a special
viewport named Simulation/Viewport.
A simulation.shader reads the viewport to compute the next frame and writes the result back to the same viewport.
Finally, the result is shaded through the render.shader and presented on the screen.
Setup and input are handled from cellular_automata.gd.
