Split context state by locality of get/set effect Some state are purely local to the context when get or set. For example, the state of depth test does not affect and is not affected by any other state. Some state on the other hand may affect other contexts. In particular, some objects are shared between contexts of a share group, and may affect each other through the observer interface. These sets of state are separated to create a clear boundary between state that can and cannot be accessed without holding the share group lock. A follow up change removes locking from the entry points that purely access the former set of states. For the latter state, it is likely possible to access most if not all of them without holding a lock, but careful inspection is required before that can be considered. In particular, most entry points that simply bind an object are likely harmless if the ref counter is turned atomic.
