Isn't it true that to have the initial frame appear from the get-go
with some non-default attributes, one must change the X resources?  I
have a vague recollection that this was always like that, and was
never perceived as a problem.  How do you want Emacs to perform the
initialization without first creating a GUI frame, and how can it
create the first GUI frame except with the default attributes?
