GdkPaintables implementing the interface will have the [vfuncGtk.SymbolicPaintable.snapshot_symbolic] function called and have the colors for drawing symbolic icons passed. At least 4 colors are guaranteed to be passed every time.

These 4 colors are the foreground color, and the colors to use for errors, warnings and success information in that order.
