We were leaking the builder in the css blendmodes demo,
by creating a ref cycle. This was showing up as
the list entry not going back to upright after
closing the window.
gtk+/demos/gtk-demo/css_blendmodes.c: In function ‘update_css_for_blend_mode’:
gtk+/demos/gtk-demo/css_blendmodes.c:49:26: error: format not a string literal, argument types not checked [-Werror=format-nonliteral]

After introducing the CSS blend mode enum values and including

This patch adds a new demo to gtk3-demo which shows how the
background-blend-mode CSS property works.
