I've made changes that allow (not force) the merging of shader stages into one invokation of glassful. Each stage's main is marked by an attribute of the stage. Everything besides a stage's main is copied into every stage, not including other stages' mains.
Function parameters not mut become in values in glsl, and parameters marked mut become out values, and if there's a return value, then that becomes the very last out value.
A couple uppercase types are converted into glsl types as well, including Pnt*, Vec*, Mat* into their (lowercase) glsl counterparts. The lowercase versions could still be used for function syntax if that is clearer.
My changes to the README.md say more.
Be warned: shaders.rs has alot of things commented out, I've been playing with syntax there. But, what I've outlined should work.
