Well, this causes bug #153, #94 and another one or two other reports 
I've see on the list.

The style^.colormap is not nil and the foreground.pixel value returned 
by these is zero, when it's btnface or anything - and it works 
flawlessly on my system making me wonder if that's being used at all.  
In fact, this isn't used until the theme is actually used to draw the 
data on the screen, correct?  And since on mine, the pixel is always 
zero, I'm guessing it's not being used at all.

Anything you want me to look for?
