    GTK: use Cairo to read X font bitmaps from server
    
    When using an X server-side font with Cairo rendering, PuTTY takes the
    rather horrible approach of rendering each glyph it uses into a depth-1
    Pixmap and then copying the result into a Cairo surface that it uses
    every time it wants to display that glyph.
    
    Heretofore, the conversion of the Pixmap into a Cairo surface was done
    by downloading it using XGetImage() and then manually re-arringing the
    bits into a suitable form for Cairo.  But Cairo has a way of turning an
    X Drawable (including a Pixmap) into a surface, and then it's just a
    case of copying one surface to another using cairo_paint().  So that's
    what PuTTY does now and the process is a little less unpleasant than it
    was.
