Yes and no.  You might think that, just because (a) by default, face
`region' does not specify a foreground color and (b) most font locking
(maybe all default font-locking) does not affect the background.

But this is the point: does the selection highlighting take precedence
over the underlying text highlighting (syntax highlighting or other)?

My guess is that in *all* of the cases you cite the answer is yes.
Selection highlighting _should_ take precedence, so you can tell
clearly which text has been selected.  When you are selecting text,
that is generally more important than other highlighting considerations.

I'm not sure what you mean by that.  Color theme was not integrated
into Emacs.  It is still a separate library (and it still works
with Emacs 24.4).  What CYD did was to enhance Emacs custom themes
to do some of what color themes do (in a different way), and to do
some things that color themes do not do.  `color-theme.el' is here:
http://www.nongnu.org/color-theme .  See also

It was lost in the context you describe (IIUC), because the platform
provided a bad default color for the `region' background.  This was
not the right "fix" for that problem, IMO (IIUC).
