Sorry, I haven't paid attention to how we store text. So it shouldn't
be an issue.

What I was talking about as in the tests/tab.c function create_tabcontrol
besides creating tab control itself, inserts three tabs with text. With
first tab being "Tab 123". Even when you not specify "TCIF_TEXT" tab still
has that text in it, it's just not displayed.

As-is (no changes) your test fails for me. Try setting some common font
with known size. BTW I tried that and it didn't work right. So we have some other
problems here.

No, I don't have such a case. The problem is it's not exactly right. And some of
your tests fail for me. I don't think AJ will except you patch if it doesn't pass
tests.
