Subject: [PATCH] Altering course. The only remaining goal of the recode is to
 isolate the cursor glyphs and process them separately.

 TODO:
 
 Reformulate the basis
-  https://buf.com/films/the-matrix-resurrections
-  Rain pass frag's output should match its debug view output
-  The post-bloom passes should apply brightness, contrast, and handle effects
-    r: cursor, g: long tail, b: short tail, a: maybe effects data goes here? we'll see
-    But, the texture format beyond the rain pass is 8-bit. Something to watch out for.
-  Create new, simpler default colorizer
-    Config properties: Cursor color, long tail color, short tail color
-  Figure out what to do with the thunder and ripple
+  Separate cursor and non-cursor parts of the code into rain pass output channels
+    Downstream passes can add them or color them separately
+  Add cursorColor to config
+    Switch operator/resurrections/classic to this
   Tune ALL the versions!
-  Find a way to support the old stuff?
   Migrate to WebGPU

   Why is it brighter than the regl version?
