Struct Version16Dot16 

pub struct Version16Dot16(/* private fields */);

An OpenType Version16Dot16 version.

The upper 16 bits comprise a major version number, and the highest-order nibble (4 bits) of the lower 16 bits comprises a minor version number (0..=9 range). Simply put, the major version is in 0xFFFF0000, and the minor version is in 0x0000F000.
