This is bad, very bad :-(
It is not compatible with our tristate visible and
it should never ever change the visibility for us, this leads to
the frame-freeze problem under fvwm because with the pager
Mappedness != Viewability != Visibility != Emacs f->visible
This first unequalness is the reason for the frame freezing problem
under fvwm (it happens when the frame is another fvwm-page)
The second unequalness happen when it is on the same fvwm-page
but in an invisible part of the visible screen.
For now we just return the XEmacs internal value --- which might not be up
to date. Is that a problem? ---. Otherwise we should
use async visibility like in standard Emacs.

Plist of default frame-creation properties for X frames.
These override what is specified in the resource database and in
`default-frame-plist', but are overridden by the arguments to the
particular call to `make-frame'.
Note: In many cases, properties of a frame are available as specifiers
instead of through the frame-properties mechanism.
Here is a list of recognized frame properties, other than those
documented in `set-frame-properties' (they can be queried and
set at any time, except as otherwise noted):
window-id The X window ID corresponding to the
frame. May be set only at startup, and
only if external widget support was
compiled in; doing so causes the frame
to be created as an "external widget"
in another program that uses an existing
window in the program rather than creating
a new one.
initially-unmapped If non-nil, the frame will not be visible
when it is created. In this case, you
need to call `make-frame-visible' to make
the frame appear.
popup If non-nil, it should be a frame, and this
frame will be created as a "popup" frame
whose parent is the given frame. This
will make the window manager treat the
frame as a dialog box, which may entail
doing different things (e.g. not asking
for positioning, and not iconifying
separate from its parent).
override-redirect If non-nil, the frame will not be subject to
window-manager control. In particular, it
will lack decorations, for more attractive
appearance of balloon help, aka tooltips.
inter-line-space Not currently implemented.
toolbar-shadow-thickness Thickness of toolbar shadows.
background-toolbar-color Color of toolbar background.
bottom-toolbar-shadow-color Color of bottom shadows on toolbars.
(*Not* specific to the bottom-toolbar.)
top-toolbar-shadow-color Color of top shadows on toolbars.
(*Not* specific to the top-toolbar.)
internal-border-width Width of internal border around text area.
border-width Width of external border around text area.
top Y position (in pixels) of the upper-left
outermost corner of the frame (i.e. the
upper-left of the window-manager
decorations).
left X position (in pixels) of the upper-left
outermost corner of the frame (i.e. the
upper-left of the window-manager
decorations).
border-color Color of external border around text area.
cursor-color Color of text cursor.
See also `default-frame-plist', which specifies properties which apply
to all frames, not just X frames.
