[REBOL] Re: arguments from/to request-font

would go nicely with the other request-* functions. But I'm not sure about
the input and output. Currently it takes no arguments, and returns a font
object, or None if canceled. This is probably not very useful in most
situations, so I'd like to hear some opinions on this.
That sounds good to me.

the font. If there's no previous formatting, you wouldn't need to pass an
argument, so the current function (which btw remembers the current state)
would work. This hardly seems like a good example though.

Why not a refinement to specify a existing style? Like:
request-font: func [/font font-object [object!]] [ ; etcetera.
Then in the function set up the display so that it matches passed in
font-object. If there's no changes, 'request-font returns 'none, if the user
changes, the new font-object is returned.
Just my opinion.
