* In a previous update in 2021 many copyright ranges were truncated
accidentally, and some files have been copy-pasted with wrong years. These
dates have been fixed based on git history and original copyright messages.
* These .py wrappers are relevant for the non-builtin path, but since we
use -builtin they serve no purpose except to make things more complex.
* So instead we make the module directly exported as 'module' instead of
'_module'.
* On windows there's no conflict because we have renderdoc.dll vs
renderdoc.pyd. On linux it's librenderdoc.so vs renderdoc.so.
* To prevent supporting files like .lib / .pdb from conflicting on
windows we build the python modules into a subdirectory. They're not
ever used by the UI (it links in the bindings directly).
* 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.
* SWIG outputs two files - renderdoc_python.cpp with the main actual
wrapping code, and renderdoc.py a small module that does some
bootstrapping on python side.
* We use a custom version of SWIG that generates strong/typed enums in
python based on enum classes, so in cmake we add this custom swig
fork as an external project and compile it before generating the
wrappers. On windows there's a committed version of the SWIG binary
that gets run directly from the .pro or .vcxproj.
* The renderdoc.py gets embedded as a resource on windows or as a C
generated unsigned char array via include-bin on other platforms, so
that we can insert it into the python context without needing it to
sit around on disk somewhere in sys.path
