Refactoring pattern: 1. guard the existing constructor(readbuffer) with the legacy build-flag 2. If you are a instancable subclass, implement CreateProc(readbuffer) to create a new instances from the buffer params (or return NULL). If you're a shader subclass 1. You must read/write the local matrix if your class accepts that in its factory/constructor, else ignore it.
