Detailed Description

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.
