Some backgrounds don't fully fill the screen. For those backgrounds it's important to paint a color behind them to fill in the gaps. This commit checks whether or not the background image textures take up the entire monitor, and in the event they don't, draws a color behind them (such as it would do if the background were translucent). https://bugzilla.gnome.org/show_bug.cgi?id=754476
