From newfeatures:

- new scripting function:
textheight(zoom,font,style) calculates
the height of text displayed with the
given zoom factor, font name and style;
textheight(1,,) gives the height of
the standard font used for showimg/showtext;
the style is a string with the letters
b (bold), or i (italic), the other styles
don't really make sense - the font name
and font style are generaly not influencing
the height a lot
