Little demo screenshot

of rendering full-featured text to Gdk canvas.

It is done with latest gnome-print (testprint4). Speed is reasonable.

The light border around font is due to shortcomings of Gt1/libart
rendering - everything is rendered aa, but we cannot do that on X without
HUGE performance loss. Hopefully it will be fixed, when we move gnome-font
to FreeType2.
