Summary: Lighting state isn't respected on transparent objects

Initial Comment:
The lighting state isn't restored when rendering transparent 
primitives.

There may already be enough information saved in the 
TQ3TransparentPrim struct to get proper lighting (in the 
"illumination" member)

Fixing this could be as simple as adding the following to 
ir_geom_transparent_render:

	if (thePrim->illumination == kQ3IlluminationTypeNULL)
		{
		glDisable(GL_LIGHTING);
		glDisable(GL_COLOR_MATERIAL);
		}
	else
		{
		glEnable(GL_LIGHTING);
		glEnable(GL_COLOR_MATERIAL);
		}
	}

...but the state should be saved between primitives and only 
changed when needed since they will likely be drawn in large 
groups that are either lit, or unlit.

Note: If using the workaround above, be sure to enable the GL_LIGHTING 
state for the specular pass, and before IRTransBuffer_Draw returns.
