[glabels] Embed the text in the printstream as text rather that as an outline

[Jim Evins <jimevins src gnome org>]

commit 063afbdeece38750044f2462837246bb1c8346c6
Author: James Cloos <cloos jhcloos com>

    Embed the text in the printstream as text rather that as an outline
    
    Fixes bug #702783.  Render text directly using pango-cairo API instead of
    filling text outline path.  Original patch modified to still use path to test
    for selection.
