A google search leads you, among others, to the OpenType specification: http://www.microsoft.com/typography/otspec/otff.htm To say it with other words: SFNT is a generic font wrapper format which can contain different font formats. For example, both TrueType and CFF fonts can be represented in SFNT format; the former uses second order, the latter third order Bezier curves. Compare this to the various Video wrapper formats like AVI which can contain zillions of different Video codecs. >> contain at least three different values that can be used for >> vertical line spacing. The three different values have slightly >> different meanings and can lead to wildly different line spacings. > > Three different values ? George talks about SFNT, not about FreeType. Here is a reference to the Vertical Metrics How-To which hopefully explains the problem: http://typophile.com/node/13081?
