background: Don't realize() this immediately - only start the image gathering thread during initialization.
Wait for the main window to be realized before passing its cairo surface to the background object and drawing the background for the first time. We also need to make sure in our background's size_allocate function to abort if we're not really active yet (no GdkWindow realized, and no AnimateTimer yet). Moved some background init stuff from the main window to the background class for clarity, and removed the default_background setting - it is already grabbing the default color in Background's class init. Obtained (and modified) from the following slick-greeter commits: d2a7122d731c0f19f502a9efba1feee651bcfa7c d4a2a94eb7120393bb225b680fdfecf5c1d3c4ea 941ecbc5dcb4e7a072c1ca8816d9678f59a96418 Adaptations by: Mike Gabriel <mike.gabriel@das-netzwerkteam.de>
