/*
 * Fitz display tree text node.
 *
 * The text node is an optimization to reference glyphs in a font resource
 * and specifying an individual transform matrix for each one.
 *
 * The trm field contains the a, b, c and d coefficients.
 * The e and f coefficients come from the individual elements,
 * together they form the transform matrix for the glyph.
 *
 * Glyphs are referenced by glyph ID.
 * The Unicode text equivalent is kept in a separate array
 * with indexes into the glyph array.
