Design plugin mechanism

[zokrezyl]

Though with a risk of bloat, it may make sense to design/implement a plugin mechanism that would allow the injection of different variables (attributes/uniforms) into the shaders, for instance:

• You may want to visualise a shader on the terminal that is consuming Jack Audio (or any other audio) samples and displaying the FFT or the waves itself
• You may want to visualise different resource usage (CPU, memory, etc)

This data could be obviously made available through the existing mechanism, but this would mean that the client program would need to run continuously to feed the data and would put the burden of implementing the source of data on the client side.
