This is a program to test the features of libschrift, a lightweight TrueType font rendering library. Unlike the demos in libschrift, show.c does not depend on any graphics environment: it generates a PGM file, which can be viewed virtually everywhere.
The code in show.c is hereby placed in the public domain and also under the MIT license.
