Fixed a WebGPU sequencing issue when skipIntro=true&once=false, caused by updating the cells and intro cells in the same compute pass. The WebGPU and REGL projects are now also slightly more alike.

+Bloom comparison: WebGPU vs REGL
+  Why are they different?
+  Create a project that tests them side-by-side
+    That's right, two canvases, one regl and one webgpu
+    program them both to do the same basic ops in a floating point texture
+    display that texture
+    Retrieve the texture from the GPU and spit it out
+  Possible causes of difference

   Get rid of end pass once it's possible to copy a bgra8unorm to a canvas texture
   Switch to rgba32float somehow?
