This file contains glass materials using new features introduced in POV 3.1 and 3.5. The old glass.inc file is
still included for backwards compatibility (it is named glass_old.inc, and is included by glass.inc, so you do not
need to change any scenes), but these materials will give more realistic results.

This file contains glass textures for POV-Ray versions 3.1 and earlier. These textures do not take advantage of the
new features introduced with POV-Ray 3.5 and are included for backwards compatability, you will get better results
with the materials in glass.inc.

These textures are designed to be used with the I_Glass interior, also defined in this file.
