VAO Cache
Each GLBatch has a small cache of VAO objects that are used to avoid VAO reconfiguration. TODO(fclem): Could be revisited to avoid so much cross references.

Detailed Description

VAO management: remembers all geometry state (vertex attribute bindings & element buffer) for each shader interface. Start with a static number of VAO's and fallback to dynamic count if necessary. Once a batch goes dynamic it does not go back.
