The NLVBCKeyCaps property defines flags indicating the available driver specific color key capabilities for nonlocal to local video memory blits in a way similar to TDDCaps::CKeyCaps.
Only the blit related flags of this property should be used.
The described effect applies when the flag is set.

DDCKEYCAPS_DESTBLT
Support for RGB blitting while using a color key to identify replacable pixels of the destination surface is availaible.

DDCKEYCAPS_DESTBLTCLRSPACE
Support for RGB blitting while using a color space to identify replacable pixels of the destination surface is availaible.

DDCKEYCAPS_DESTBLTCLRSPACEYUV
Support for YUV blitting while using a color key to identify replacable pixels of the destination surface is availaible.

DDCKEYCAPS_DESTBLTYUV
Support for YUV blitting while using a color key to identify replacable pixels of the destination surface is availaible.

DDCKEYCAPS_DESTOVERLAY
Support for RGB overlaying while using a color key to identify replacable pixels of the destination surface is availaible.
