3D models: Problems with the `d` interpretation (dissolve vs transparency)

The current code interprets the d attribute in raw_obj as transparency, but looking at some references this seems to be another thing called dissolve, which is related to transparency, but isn't the same.

The part C115366 (SW-TH_SPEF110100) has d=1 and generates a WRL with transparency 1, making the whole object invisible.

I think the exporter should avoid using the d parameter. Do you have examples where d is used in the same way as transparency? I tried with various LEDs with transparent lenses and all used d=0.
