Capture/Replay: Don't serialize shader refcount with context The shader and program reference count is not an OpenGL state, it is only an implementation dependent value and should, therefore, not be part of the context serialization. In fact, it is actually misleading, because for shared contexts its value depends on the state of all contexts and not just the current one. Especially with MEC this may lead to validation errors, because a sequence Context 1 (shared): create program A Context 2: use program A -> start MEC will result in a refcount of "1" when the state of context 1 is serialized during MEC startup, because at this time context 2 already holds a reference. However, when the valiation checkpoint at the end of the setup for context 1 is executed during replay, then the setup for context 2 has not yet been run and the refcount will be "0".
