* 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).
* This version contains the fix for sphinx-doc/sphinx#2550 so we want to
assume it is present and tidy up all the external links. However if
needed (and you don't care about the external links being broken) you
can locally remove this version requirement.
