PFND3DWDDM2_6DDI_PREPARE_SCANOUT_TRANSFORMATION callback function (d3d10umddi.h)
Invokes the driver to schedule work to perform the necessary transformations from the input resource, to the "shadow" allocation which will actually be scanned out. The runtime may request that the driver only update a sub-region, if only a small portion of the resource has changed since the last time this was invoked.
