+ 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).
+ 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.
