    14 * Description:

    15 * Tests FNTSTORE with respect to the Open Font system.

    16 * Creates a dummy rasterizer and tests font file loading and unloading and

    17 * font creation. This just exercises the way the Open Font system connects to the

    18 * 'classic' bitmap-font-only font system.
