/*
  FLW is a Font Library Wrapper abstraction designed to allow any
  number of underlying font libraries to be used through the same API.

  Functions and datatypes are loosely modeled on the FreeType font
  library.

  Which underlying font library to use is currently determined at
  compile time.
