Arguments: dialog-item
Returns whether dialog-item's coordinates are
specified in dialog-units rather than in pixels. If
true, then the dialog-item's coordinates are
measured in dialog-units, which are defined as one-fourth of a
system-font space width wide or one-eighth of a system-font
line-height high. If nil, the coordinates
are in pixels, which are the coordinates that are usually used by
common graphics.
Dialog-items will be created using pixel coordinates unless the
:dialog-units-p initarg is passed as true when
creating the dialog-item with make-instance.
Because the system-font varies from one machine to the next, using dialog-units is discouraged.
