Vertical Centering Text

[Ivers, Doug E]

I'm also interested in a function that does this accurately for all possible fonts, styles, lineHeights, etc.  This seems to me to be very useful for a one line field (such as username/password entry).
I wrote one a few months ago, but it also didn't seem to work in all cases.
I suspect one of the more experienced Revolutionaries could do this in about 5 minutes.
Any takers?
