new-named-style

Creates a new named style, unless the name is already being used.

• (send a-wx:style-list new-named-style name like-style) -> wx:style% object
      name : string
      like-style : wx:style% object

  If name is already being used, then like-style is ignored and the old style associated to the name is returned. Otherwise, a new style is created for name with the same characteristics (i.e., the same base style and same style delta or shift style) as like-style.

  The like-style style must be in this style list, otherwise the named style is derived from the basic style will an empty style delta.
