Doh! The short version didn't work eh ;)

I can take this one if nobody wants it.

Lofton, you state that WebCGM is pretty unspecified here... what about
ISO CGM, what _does it_ specify? I wouldn't mind a couple of pointers
in the ISO CGM spec as a starting point:

Section 2.5.3 Color and transparency of Webcgm 2.0 states:
- "The normal behavior of CGM:1999 viewers is to render later occurring
primitives completely opaquely on top of earlier primitives." Where is
this said in CGM:1999?

- the alpha-transparency Escape element... where is that element
specified? Can we get the wording?

- same question for sRGB/sRGBA, RGB/RGBA.

Would it be fair to say that Esc 45 maps to the 'opacity' attribute in
SVG?
