Syntax

typedef enum DXGI_DDI_MULTIPLANE_OVERLAY_BLEND {
  DXGI_DDI_MULTIPLANE_OVERLAY_BLEND_OPAQUE,
  DXGI_DDI_MULTIPLANE_OVERLAY_BLEND_ALPHABLEND
} ;


`DXGI_DDI_MULTIPLANE_OVERLAY_BLEND_OPAQUE` The overlay plane should ignore data in the alpha channel and make the blended plane entirely opaque.
`DXGI_DDI_MULTIPLANE_OVERLAY_BLEND_ALPHABLEND` The overlay plane should use the pre-multiplied alpha channel in this plane to blend it with the plane beneath.
