But use /usr/bin/env python in the shebang. This obviously allows the
script to work in environments where python is not installed in /usr/bin
say, on Windows where it's somewhere in the system outside of the msys fs.

The assembly shader arrays are supposed to be NULL-terminated arrays of
pointers. My system was very kind and never crashed but this can't be
expected in the wild where evil segfaults reign.
Yes, this is embarassing.

Things are a bit convoluted:
* we want to keep GLSL shaders (eg OpenGL ES 2.0 does not have
the GL_ARB_fragment_program extension)
* we want to default to assembly fragment programs as they will support
as broader range of hardware
Now, those fragment programs are written in Cg, compiled with the Cg
compiler and its arbfp1 profile and then turned into a header file
thanks to a small python script. Sounds fun isn't it?
As people may not want to install the Cg compiler, let's commit the
actual fragment program. The configure script will detect if you have
cgc and add targets to build the pso file accordingly.
