// from the MeasureString method includes some extra spacing
// for descenders and whitespace. We want ONLY the height from
// the BASELINE (which is the line which all caps sit). Any
// characters with descenders drop below the baseline. To
// calculate the height above the baseline, use the
// GetCellAscent method. Since GetCellAscent returns a Design
// Metric value it must be converted to pixels, and scaled for
// the font size.

// over the baseline nicely -- like caps. Characters with descenders
// look odd. To fix that uncomment the two lines below, which
// then reflect across the lowest descender height.
