Re: [PyOpenGL-Devel] new semi-release soon.

Should be, but it'll be dog slow without serious optimisations (which is 
part of why I need to re-tool the traversals).  Even in C the author of 
the algo suggests it requires lots of optimisations.  (It does 1+Nx2 
full rendering passes (opaque+transparent) for N lights in the scene + 
2xM shadow-volume-rendering passes).  Will require ways to auto-cull 
shapes according to light cones/spheres, and ways to test for 
shadow-volume intersections with the frustum (among othe requirements). 
 That all requires mechanisms for manipulating/calculating relative 
scenegraph path matrices and the like.  Should have those tools anyway, 
but I haven't needed them until now in OpenGLContext.

Oh well, such is life,
Mike
