 * \file enum_sizes.cpp
 * Validate the generated code in indirect_size.c
 *
 * The functions in indirect_size.c determine how many data values are
 * associated with each enumerant that can be passed to various OpenGL
 * functions.  Tests in this file probe each function in indirect_size.c with
 * each of the possible valid enums and verify that the correct size is
 * returned.  Tests in this file also probe each function in indirect_size.c
 * with a larger number of \b invalid enums and verify that zero is returned.
