Currently, the debug pipeline wrappers look like:

wrapper() {
  checkContext();
  downstreamGL4bc.wrappedFunction(arg0,arg1,arg2...);
  String txt = new String("a large debug string + all args")
  checkGLError(txt);
}

Change to a format based string, and add a check-only fucntion
to allow an allocation-free fastpath for the success cases:

wrapper() {
  checkContext();
  downstreamGL4bc.glShaderOp1EXT(arg0,arg1,arg2);
  int err = checkGLError();
  if (err != GL_NO_ERROR) {
    writeGLError(err, "%s(<int> 0x%X, <int> 0x%X, <int> 0x%X)",
                 "glShaderOp1EXT", arg0, arg1, arg2);
  }
}
