  Pass the Command when sync'ing dirty objects
  
  A new enum is being created that contains command types, which are then
  passed to each dirty object when they are synced. This allows the
  syncState() methods to perform special handling for each command type.
  
  This change is in preparation for optimizing resolving multisample
  images with glBlit, since the render pass needs to be updated before
  it's ended.
