Plist of default frame-creation properties for w32 frames.
These override what is specified 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):

  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).
  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).

See also `default-frame-plist', which specifies properties which apply
to all frames, not just w32 frames.
