Remarks
To display quad layers, an application creates the necessary HolographicQuadLayer instances and adds them to a HolographicCamera's mutable QuadLayers list. To synchronize a retained quad layer update with a given immediate-mode holographic frame, an application requests an HolographicQuadLayerUpdateParameters instance from that frame by calling HolographicFrame.GetQuadLayerUpdateParameters. Any updates requested on that HolographicQuadLayerUpdateParameters instance will apply starting in that frame.
Note
The AcquireBufferToUpdateContent or AcquireBufferToUpdateContentWithHardwareProtection method must be called when updating a HolographicQuadLayer object for the first time.
