26  * Sync object management.
28  * Unlike textures and other objects that are shared between contexts, sync
30  * and delete behavior of sync objects is slightly different.  References to
31  * sync objects are added:
45  * As with shader objects, sync object names become invalid as soon as
78  * Allocate/init the context state related to sync objects.
88  * Free the context state related to sync objects.
145     *    - sync is unsignaled when ClientWaitSync is called,  in __client_wait_sync()
149     *    immediately after the creation of sync.  in __client_wait_sync()
164  * Check if the given sync object is:
166  *  - not in sync objects hash table
169  * Returns the internal gl_sync_object pointer if the sync object is valid
174  * could delete the sync object while you are still working on it.
