Disable texture strip atlasing for DDL

Ultimately we will want to perform inline and ASAP uploads for the
texture strip atlas. Unfortunately, that functionality relies on the
existance of the flushState (which we don't have for the opList-based
DDL implementation). For now we will punt and try storing the individual
texture strips in their own image-based texture proxy for DDLs.
