The basic idea here is to "link" together a series of different operation kernels by constructing a list of kernel addresses into an SwsOpChain. Each kernel will load the address of the next kernel (the "continuation") from this struct, and jump directly into it; using an internal function signature that is an implementation detail of the specific backend. Private data for each kernel.
