It actually does affect screen display, Joel.

If you google gdi gdiplus padding measurestring quickly, you will find innumerable references like the following:

---
Graphics.MeasureString doesn't return the right size
microsoft.public.dotnet.framework.windowsforms
I'm trying to determine if I have to show a tooltip for a listbox item by comparing the width of the item with the width returned by MeasureString for the item's text. But MeasureString seems to return a slightly higher value than the actual width. So I drew the text myself using Graphics.DrawString, and indeed, it draws it wider than the text in the listbox, even though I'm passing the Font used ...

And yes there is a technical reason, actually several, not one simple one, which is why you may not have noticed that it affects screen display.

OTOH, if you mean specifically "VFP forms", VFP doesn't use GDI+ for *everything* in screen display, so if you mean (say) textboxes there is no reason why it should be affecting that.
