GApplication now has a palette. This palette contains all the system theme colors by default, and is inherited by a new top-level GWidget. New child widgets inherit their parents palette. It is possible to override the GApplication palette, and the palette of any GWidget. The Palette object contains a bunch of colors, each corresponding to a ColorRole. Each role has a convenience getter as well. Each GWidget now has a background_role() and foreground_role(), which are then looked up in their current palette when painting. This means that you no longer alter the background color of a widget by setting it directly, rather you alter either its background role, or the widget's palette.
