* 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.
* 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.
* 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.
* 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.
* A 64-bit install has an x86 subfolder to capture 32-bit programs. If
a 32-bit program then launches a 64-bit program we need to 'promote'
back to run the original bitness to capture it.
* It's still not supported to capture 64-bit in general from just a
32-bit install as the support files aren't included.
* This also fixes the problem of capturing 32-bit programs with 64-bit
RenderDoc failing to properly insert environment variables and
error'ing when it tries to do it directly.
Notes
======
- With no clean way to do string comparisons in the C preprocessor, have a define per-platform. This avoids the clever string concatenation for determining the OS-specic bits, and allows SN-DBS to distribute builds without custom rewrite rules.
- Fix up instances of WIN32, etc., in non-3rdparty sources to refer to this.
- Move the per-platform specific bits into their own subdirs.
