[Interest] [External] Text: remove empty space at top or get its size

[Alexander Dyagilev]

Thanks for the response.

I don't see any suitable value in FontMetrics.

tightBoundingRect is helpful and can be used. But unfortunately, it does 
not take underline into account (i.e. it ignores 
FontMetrics.font.underline). I don't know if it's a bug or not. Also, 
it's very slow on Windows, as it stated in docs.
