How about the attached patch?

I'm not sure whether I'm doing right with respect to suppressing fg/bg
colors in `preview-gs-color-string', in the above case (1).  I don't
understand what role "mask" and "border" play here, so I suppressed only
"fg" and "bg" parameters.  Maybe I should disable
`preview-gs-color-string' altogether in the case (1).

This patch brings a drawback for users who customize the background
color of Emacs and use default foreground color, with unmodified
gs-9.27.  In that case, the background color of the generated images
will just be white and no longer match with Emacs.
