We would also like to refactor the common aspects of the SDL backend into a common base class to better support backends that derive from it. Architecturally this could be very elegant and allow platforms to derive from the common SDL base (inc. the OpenGL and default existing one) and future platforms could also derive from the OpenGL base etc. | We would also like to refactor the common aspects of the SDL backend into a common base class to better support backends that derive from it.
