Description
Request an update to the edge snapshot (capturing from the heightmap source). When bUpdateGPUEdgeHashes is true, it will also update the GPU Edge Hashes to match. This is set when we know the heightmap source exactly reflects the GPU texture state i.e. after reading back from GPU to CPU after a layer merge, or after UpdateResource().
