The font object for build subsets.

Used to position one glyph with respect to another.

Used to position one glyph with respect to another.

TTF files are stored in big-endian format, we need special readers and writers

Base class for the Feature Parameters tables.

Provides information about how to use the glyphs in a font to render a script or language.

Identifies the typographic feature in the OpenType font.

Specifies the second glyph in a pair and defines a ValueRecord for each glyph.
