[Fluxus] glsl shader and -x option

[Krisztián Gergely]

Hi fluxus list!

I have stumbled into some strange side-effect of the -x command line parameter.
If the fluxus is started with the -x parameter, then the shader
functions seems to fail silently.

You could try to reproduce this behavior by running the GLSL.scm with
-x. On my machine
this leads to a plane gray sphere, instead of the usual colorful dancing one.

It would be really great if you could point me in a direction to fix,
or work around this.
Also let me know if you can't reproduce the above mentioned effect,
since that may mean i do something wrong.

thank you,
Krisztián
