Method TransferImagesFromGPU

vgpu/memory.go:606–614

TransferImagesFromGPU transfers image memory from GPU to CPU for given images. the image Host.Offset *must* be accurate for the given buffer, whether its own individual buffer or the shared memory-managed buffer.

(buff vk.Buffer, imgs ...*Image)
