Default colors vs. gamma

[Alexander Malmberg]

Hi,

A common complaint about GNUstep is that it isn't pretty enough, and a 
common response in #GNUstep is "fix your gamma". Since it seems that 
most users don't set their gamma properly, I wrote the following patch:

http://w1.423.telia.com/~u42308495/alex/systemColorGamma.patch

which simply does gamma adjustments on the default system colors before 
using them. The GSSystemColorGamma default controls the gamma, and 
defaults to 1.6, which makes things bright and cheerful for 
non-gamma-adjusted users. (Users who have adjusted their gamma will want 
to set this default to 1.0 or things will be _very_ bright. :)

So, do we want to do this? If so, what do we want the default value to 
be? 1.6 is nice for users who haven't set their gamma, but not so nice 
for users who have set it; I'm not really happy about forcing users who 
have set things up properly to set a default just to tell GNUstep that 
their system is set up properly, but if this makes GNUstep prettier to 
other users, it might be worthwhile.

Thoughts?
