Thanks.

In current and future povr releases the sky_sphere emission keyword 
should instead be 'amplify'.

The 'amplify' keyword being a block oriented color multiplier vector in 
povr. These multipliers exist already to some extent under different 
keyword names and where they don't I've been adding them.

Aside: The sky_sphere's 'emission' keyword was always only a color 
vector multiplier. Backgrounds and sky_spheres always emit light in the 
radiosity sense.

No news on the -win id thing. The end of the year was both busy and 
bumpy health wise for me. Truth is I'm mostly only now getting back to 
last work left hanging last October. :-)
