RE: [R21.4] [COMMIT] Update glyph documentation

`make-glyph' returns a glyph object, and to me, the docs do say that: -------------------------- "Create a new glyph of type TYPE. A glyph in XEmacs does NOT refer to a single unit of textual display (the XEmacs term for this is \"rune\"), but rather is an object encapsulating a graphical element, such as an image or widget (an element such as a button or text field; \"widget\" is the term for this under X Windows, and it's called a \"control\" under MS Windows). This graphical element could appear in a buffer, a margin, a gutter, or a toolbar, or as a mouse pointer or an icon, for example. Creating a glyph using `make-glyph' does not specify *where* the glyph will be used, but it does specify *what* the glyph will look like. In particular, SPEC-LIST is used to specify this, and it's used to initialize the glyph's `image' property, which is an image specifier. (Note that \"image\" as used in the context of a glyph's `image' property or in the terms \"image specifier\", \"image instantiator\", or \"image instance\" does not refer to what people normally think of as an image (which in XEmacs is called a \"pixmap\"), but to any graphical element -- a pixmap, a widget, or even a block of text, when used in the places that call for a glyph.) -------------------------- Since they don't for you, David, could you tell me what kind of wording would help you? Would it be enough if the first line said "Create and return a new glyph object of type TYPE"?
