ImGui drawing code now takes place in the main thread, a snapshot of the render data is created in CMaterialSystem::SwapBuffers(), and is being rendered in the render thread right before SpinPresent(). The reason why this was necessary, is because ConVar::GetString() isn't thread safe if its not marked FCVAR_MATERIAL_SYSTEM_THREAD or FCVAR_ACCESSIBLE_FROM_THREADS, and we used it for the console suggestions window, which iterates over every ConVar, accessible from threads or not. This is overall also a better code architecture. This change also forced changes in the ImGui server browser window, which contained a bunch of threading bugs too. Engine changes: - g_pCVar is no longer exported, as this wasn't necessary in the end. - g_ThreadMainThreadID and g_ThreadServerFrameThreadID are now exported from the game executable, as these are required as soon as the DLL is loaded.
