Allows creation, management, and state queries of binary state objects. Currently they are not very useful as there is no way to wait for them efficiently. The basic trigger operation added here triggers relative to a given X screen's rendering operations. To perform this operation, fence sync objects must be tied to a screen. As Aaron Plattner pointed out, screens are identified but a drawable in X protocol, so a drawable argument is included in XSyncCreateFence(). The screen also could have been specified as part of the trigger operation. However, it is also desireable to associate a screen with fence sync objects at creation time so that the associated screen's driver can allocate any HW- specific resources needed by the fence object up front.
