We have no intention to change this but we would like to extend the default backend to take advantage of things like OpenGL, and its little brother OpenGL ES, that is becoming commonplace on the latest generations of devices. | ||
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.
