* Generally this means removing ref out parameters and instead returning
values. In a couple of cases we will want to avoid copies in future
either by returning const references (e.g. to the pipeline state which
is immutable).
* At the same time, some pointless bool return values that were always
true and didn't indicate errors have been removed. They can be added
again if an error condition comes back.
* Some free functions still have out parameters as C linkage doesn't
allow returning user types by value.
* The C# UI still invokes into C wrappers for all the C++ classes, which
handle taking the return value and doing a copy into an out parameter
still for compatibility.
* Note, this API is still in-flux and beta, so there may still be some
more changes before it's 'stable', and even then it will still be
subject to some amount of change.
* This API is then exposed to python via SWIG bindings and hides
internals that don't need to be visible, and means the actual API is
easier to work with.
* We also use this API to reduce inter-dependencies between different
windows that need to interact with each other at a high level.
* The naming is python/standard RenderDoc TitleCase method names, not
Qt style camelCase methods.

# qrenderdoc/Windows/TextureViewer.cpp
* This goes all the way back to the first iterations where these were
the only structures and 'Fetch' referred to them returning data from
the core code to the UI.
* This gives a little nicer syntax, a bit better type safety, and also
reflects better for SWIG bindings. Overall it's a minor change but
better.
* We don't update the C# UI at all, since it's soon to be removed and
not worth the effort/code churn.
* For now so we're ABI compatible with C#, all enums are uint32_t, but
that is an obvious optimisation in future to reduce struct packing.
* We avoid 'None' as an enum value, because it's a reserved word in
python so will cause problems generating bindings.
