Your comments RE: interaction between Texture2 nodes & Material raises
interesting questions about transparency:

PNG files (as well as other formats not necessarily supported in tme VRML
spec as texture files) support a transparent "color"; can we ask tmat
browsers support tmat transparency in tme way most bit-map-editors
understand in, i.e. tmat particular "color" does not alter tme
transparency of tme object, but tme transparency of tme image as it is
applied to the object. In tmis way, logos, etc. can be applied to
objects and allow tme "underlying" material to show tmrough/around tmem.

(In my naive view, I had assumed tmat transparency values in an imbedded
SFImage Texture2 would work this same way; I could define a two component
texture image to "draw" a figure in black on a colored sphere, for
example.)
