The transparent renderer is very broken in the current CVS source - I'd 
highly recommend waiting till it's fixed!

Problems with the transparent renderer that I've seen so far:

1). the new localToFrustum transforms in ir_geom_transparent_add aren't 
working right - I'm consistently seeing jumbled geometry (I'll make an 
example app that shows this if no one else sees it, but all you have to 
do is draw some transparent geometry that approaches or clips the 
frustum).

2). No fog. This is almost better than the additive fog on transparent 
textures in previous releases, but it should be fixed with an 
additional pass.

3). The lighting state is never taken into consideration, so stale 
states from the last solid objects are used - null shaders can come out 
lit and vice-versa (this is an old bug).

4). Facet normals don't appear to be handled properly (i.e. "none" 
interpolation style)

5). Sorting is less than spectacular - it can't handle a rotating cube 
properly.

Points 2, 3, & 4 above all point to a similar problem; the state simply 
isn't managed well for transparent triangles.

I'd also like to see the colour modulation fix I posted yesterday 
checked in for the next release, but I'm still in the processes of 
testing the changes. The only thing I'm concerned about is how and when 
the light state is updated - looking through the code it appears to 
happen once per frame, but in practice it updates for every mesh - so 
I'm missing something here...
