This is much better than my one paragraph attempt. Should we link to the 
page, or create an extra section in the spec for this?

Creating the low contrast icons can be done automatically as you 
suggest, so I don't think it would be a good idea to burden developers 
with having to do more work to get their application "accessible" than 
is strictly necessary.

I noticed that the "HighContrast" icon theme in GNOME is actually blank, 
and it is the icons in HighContrastLargePrint that are actually used. I 
would suggest we swap this and depreciate the LargePrint versions. I 
think we will have to bite the bullet on the 'upgrade path' problem and 
just remove them. The worst case is someone will just have to re-select 
the high contrast icon theme from the theme capplet.

However, this is a GNOME issue that needs to be addressed separately. 
For the purposes of the icon theme spec, I think we should stick to just 
HighContrast and not mention the others.
