I don't understand the question.  The Windows port reads X resources
from the Registry; why shouldn't we support that?

What kind of sharing do you have in mind?  Faces are frame-specific,
so changing a face generally affects only the frame for which it is
changed.  If the suggested sharing will defeat this, I don't think
it's a good idea.

If color-theme blindly adds faces instead of modifying existing ones,
then yes.  Does it actually do that?

See struct frame defined on frame.h, but some of its members have
variable length.
