context is not using the dvips style color mechanisms and never will 
(there is too much involved in color handling so we need full control)

why not

- make font driven color handling an option
- ignore font driven color support when x: is used?

(context users normally don't need support for color as font attribute 
so i'm happy with it being ignored when x: is used)

let the macro package worry about it; if the macro writer messes up, no 
one can blame you
