Fixed some major bugs: the WebGPU cache should store loaded images and text, never GPU resource handles; renamed renderer "formulate" to "configure"; WebGPU renderer's configure function needs early returns after each major await, in case there's a new config; the render loops are now locally stored closures; renderers now have start and stop functions; fixed bugs in the REGL and WebGPU mirror passes; WebGPU bloom pass now enforces texture dimensions are greater than zero; the react component now stores the renderer type in a useRef and returns early from renderer init awaits to prevent multiple renderers from instantiating.
