  WGSL: Rewrite input/output variables
  
  GLSL builtin variables and in/out variables correspond to WGSL's main
  function params and return value, so rewrite them accordingly.
  
  This is done by generating structs to use as main function params and
  return values, generating similar global structs, and copying the
  former into the latter so the rest of the program can just use the
  variables stored in the global structs.
