* Tacking -official onto the git hash was a hack only needed on windows,
and since we want more information it doesn't scale.
* Instead we track anything we need to know about the version in
separate variables, like whether it's a stable build or a nightly/
local build. Or if it's built by a downstream distribution then the
version number for the downstream build.
* This allows us to return complex types like byte arrays or pairs of
status & render handle.
* Also in future more introspection of the capture file will be possible
and this provides an easy extension to that without adding new entry
points.
* In python it's not as quick to get ~0U since ints aren't unsigned or
fixed size. Adding named constants makes it easier for people to use
the right values, and C++ users can still pass ~0U.
* 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.
* Things like addressing modes, stencil operations, and other things the
UI didn't need to know about previously were only exposed as string
values to be passed through and displayed.
* Now we describe these with enums so the API can be properly
introspected and used by consumers that might want to know the actual
values of these states.
* 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.
* The functions are still exported and that's all renderdocui cares for.
* The interface is no longer to be used so gets in the way of the
generated SWIG bindings.
* For SWIG bindings we need something that will go type -> string name
so we can look up the SWIG type in a template to convert elements in
arrays.
* An upcoming refactor will contain this kind of typename for proper
reflection, so to minimise code churn and avoid adding multiple new
solutions for the same kind of thing, we borrow the macro name and
implement it for the API structs we need.
* Moving into a namespace makes it easier to give the structs non-clumsy
names while still being unique and not overlapping with the other API
pipeline states.
* SWIG doesn't handle nested structs conversion to python, so we are
going to split out all structs. Mostly this is the case in the
pipeline state structs, but this commit splits out a few in the rest
of the API.
