  Centralize renderer limitations for non-conformant renderers
  
  Some renderer configurations (e.g. D3D11 Feature Level 9_3) have
  some limitations and aren't quite conformant. This change
  generates errors when applications hit these limitations, and
  informs developers that they must work around them.
