GPUUpload/GPUDownload

std.GPUUpload(vnode: all clip)

Returns a GPU resident version of clip, transferring each requested frame to the core’s Vulkan device. The upload is also inserted automatically, with a log message, whenever a CPU clip is passed to a filter expecting a GPU clip, so calling it explicitly is only needed to control where in the graph the transfer happens.

std.GPUDownload(vnode: all clip)

Returns a CPU resident version of clip, transferring every plane back from the device.

If a clip is already in the requested location it does nothing.
