This patch implements a bit more of device-font-text-style, while
ignoring the spec's requirement that they behave, apart from merging,
like normal text styles -- that is, that they have a family, size and
face.  (The requirements for family and face are pretty nonsensical,
but it is clear that a device font needs to acquire size information
at some point).

This patch allows use of device-font-text-style in the experimental
freetype backend; with it, you can do

  (with-text-style (medium (make-device-font-text-style 
                            (port *application-frame*) 
                            "/Fonts/tabcode.ttf"))
    ...)

and have that font active for draw-text for the dynamic extent.

If anyone has any ideas about how to make this better or more
generalizeable, that would be great -- particularly since we're also
going to want Postscript support for this...

Cheers,

Christophe
