DXGKDDI_CANCELQUEUEDFLIPS callback function (d3dkmddi.h)

In the hardware flip queue model, the OS calls a display miniport driver's DXGKDDI_CANCELQUEUEDFLIPS function to synchronously cancel previously queued flips. This function was superseded by DXGKDDI_CANCELFLIPS starting in WDDM 3.0.

)
{...}
