Scaleform::Render::FenceType

enum FenceType {
  FenceType_Vertex,
  FenceType_Fragment
};

FenceType represents the type of fence. For most platforms, these are equivalent, because fragment and vertex processing happen in parallel; fences are not 'passed' until both have completed. However, on NGP for example, there are separate vertex and fragment passes, so they are not equivalent on those systems.
