Tabs with theme

[dbdante]

Thanks for the fantastic job on bringing fltk to rust.
I have an issue with tabs and themes and not sure how to address it. The tabs seems to have a line underneath the tab header when a theme is applied. This does not look right.
Below is a screenshot:

Without applying the dark widget or any other theme, this looks right.

I can paste relevant code if needed. This is on Windows if it matters.

I believe all of the widget themes use app::Scheme::GTK which seems to be the source of the issue. Changing it to app::Scheme::Base worked for me. Its not limited to GTK. Aero and others have this issue as well. Not sure if this is intended.

Thank you for your kind words.
I’ll need to investigate why this happens. My primary suspect is the Tabs default frametype drawing. I’ll try to check this weekend.
