Some of them. The defaults of highlight color for example I remember were
imported.
The scrollbar settings, I recall, are not.

Rather than fixing this in a piecemeal fashion, an Emacs port that uses
higher-level system APIs (and does not implement Emacs settings for such UI
details) would be the more realistic option. It could co-exist with the
low-level Emacs port.
