To quote the Qt documentation for QFileDialog::setNameFilters:

Admittedly, one of these usages is Windows-only and we are using the
native file dialog there, but we might as well be consistent.
Instead of manually specifying the default extension, just grab the
first one from each filter. We can only specify one at a time, so
update it whenever the selected filter changes.
In most of these cases, the open file dialog won't even display a file
without the proper extension, so this helps ensure the user doesn't
accidentally misplace their files. The one exception is *.rdc, which
could be found without the extension, but could not be opened.
* The former is only needed inside tp_init of a new object. Instead when
we want to pass in and own a pointer, we use SWIG_POINTER_OWN.
* This also removes the need to pass 'self' all the way down in
ConvertToPy which tidies up a lot of code.
* This allows a buidler to customise from e.g. /usr/lib/librenderdoc.so
to /usr/lib/renderdoc/librenderdoc.so - which is harmless since the
library is 'private' and not intended to be linked against directly.
* If there's a variable which is unused and has no binding declared, it
will be sorted to the end of the list and given a binding of 0. We
don't want to let this override a valid binding for 0, so make sure we
prioritise any variable which is marked as used over one that is
unused.
* Instead of checking on the filename, we look for a specially named
exported symbol somewhere in a module that's already loaded.
* This allows us to mark the python module as a replay program, so if
it's loaded into the python interpreter it will be able to use the
replay API.
* For D3D this is overkill as we just stuff the uint32_t flags into a
string. However for SPIR-V this will let us store the parameters from
an OpModuleProcessed.
