bindgen needs a way to block a type alias without blocking things that depend on it

So there's SDL2, and on linux it has some X11 support, and one of those types is Window.

Window is a super common word, one which I want to use in the higher level library in fact, and so really I'd like a way to not have it be in the library when you do a glob import (because there's a gazillion items, so you want the ability to glob import). However, if I blacklist the type things that depend on it have errors.

Since it's only a type alias, not a whole struct and all, can there be a way to have it removed from the output and then have the type that it's standing in for be used everywhere it would have been used?

The issue names no files, tests, or entry points. Start by locating bindgen's handling of C type aliases and the dependency logic used when aliases are blacklisted. Define done as suppressing the alias while preserving valid uses of the underlying type, with coverage for dependent declarations and glob-import output.
