I have modified the test 1-2 hours ago.

Well, then I can not explain some browser passing and failing while
declaring the same browser default font.

For this test:

I declare DejaVu Serif as default font in all browsers I use under KDE
4.9.0; I declare Times New Roman as default font in all browsers under
Windows XP Pro SP3.

Opera 12.0.1 passes this test under Linux KDE 4.9.0 and Windows XP Pro
SP3.  Safari 5.1.7 under Windows XP Pro SP3 fails this test.
Chrome 21.0.1180.75 under Linux KDE 4.9.0 passes this test.

That's a 1px vertical gap, right?

Over here, I get a 4px (or so) horizontal offset under Linux KDE for the
beforementioned browsers; such horizontal offset seems bigger, wider
under Windows XP Pro SP3. I can attach (or upload) more screenshots if
