I haven't worked with Chromium, but the main C++ code-base at Google is like this for the most part too (especially the core stuff).
The C++ culture at Google is amazing, and proof that large-scale C++ can actually be really nice if you stay within best practices. It takes a lot of effort and experience from a lot of knowledgeable people to craft these practices, but thankfully Google publishes its C++ style guide (http://google-styleguide.googlecode.com/svn/trunk/cppguide.x...) so that everyone can reap the benefits of this.
