[D11] #1830, remove the named grab pass, this could worsen performance in game but in practice it doesn't because the engine batches blurred icons together, so no extra grab passes are added by doing this, although that batching is somewhat suspect and not technically right. Anyway, a few more grab passes would be fine in the frontend, and the in-game blurring will eventually be done completely differently to this, so it doesn't matter too much.
