As promised, glls now supports the (optional) automatic generation of functions 
for rendering pipelines. This function generation manifests differently 
depending on whether your file is compiled or evaluated. When compiled, 
rendering functions are compiled to efficient C. When evaluated, a generic (not 
remotely efficient) rendering function is used.

glls also now provides support for dynamic reevaluating of pipelines in such a 
way that the old program object ID is reused, so that your scene is instantly 

Two new examples were added (texture.scm and interactive.scm) to illustrate 
these new features:

And, of course, the documentation describes these changes in detail:

glls is now a rather unique library for shader creation. Not only does it 
provide far tighter integration into the host language than the usual method 
for working with shaders, but it also makes few to zero speed sacrifices (when 
compared to hand-written C) even when the automatically generated rendering 
functions are used. These features were very much born out of Chicken’s unique 
strengths – I really can’t imagine combining them in any other language or even 
Scheme implementation. A big thanks to the Chicken team for creating a language 
and environment where this sort of thing is possible!
