Summary: Specular highlights in transparent pass aren't sorted

Initial Comment:
The specular highlight pass for transparent triangles waits till all 
the transparent triangles are drawn, then blends highlights after 
the fact. The problem is, the highlights are drawn on top of 
everything in the colour buffer, so highlights on transparent 
triangles that are occluded by other transparent triangles are 
drawn full strength when they should appear to be filtered through 
the triangle in front.

A solution would be to draw each Phong shaded primitive in two 
passes when first sorted, rather than drawing the entire list of 
Phong shaded primitives as a second self-contained pass.
