+Implementation class for SalGraphics.
+
+This class allows having an implementation of drawing calls that is separate from SalGraphics,
+and SalGraphics can forward all such calls to SalGraphicsImpl. For example X11SalGraphics
+may internally use either Xlib-based X11SalGraphicsImpl or Skia-based SkiaSalGraphicsImpl,
+and the latter may be used also by other SalGraphics implementations. All the functions
+here should be implementations of the relevant SalGraphics functions.
