Simple program that uses the ARB_get_program_binary extension to retrieve the
internal representation of an OpenGL GLSL shader.  This was mostly meant as an
experiment to see what intermediate language GPU drivers compiled GLSL to.

Note that while ARB_get_program_binary is core in OpenGL 4, it's still available
as an extension on most OpenGL 3 implementations.

Includes the Pez library by Philip Rideout.

Requires GLEW >= 1.5.6, or compilation will fail complaining about undefined
symbols from ARB_get_program_binary.
