@code{display-type} are also meaningful. If the terminal supports
frame transparency, the parameter @code{alpha} is also meaningful.
By default, frame parameters are saved and restored by the desktop
library functions (@pxref{Desktop Save Mode}) when the variable
@code{desktop-restore-frames} is non-@code{nil}. It's the

@code{frameset-persistent-filter-alist} to avoid that they get
meaningless or even harmful values in restored sessions.
