If i use "Arial" in most cases the text is vertical centerd ok in gets. But when i use z.B. "Segoe UI" (WITH THE SAME HEIGHT) the text is deeper on the line and in the get in some cases the space between get-top and text-top are to great to show the complete height of the text! ( is tmInternalLeading to respect??? )
This gives often a ugly look!
Or try to center a "7" in a circle with different fonts. You see, that the vertical position changes with the used font.
