Patch from David Carre: I fixed a bug in the "SDL_DestroyRenderer()" function in the pandora x11 renderer (in fact the bug was in the "X11_GLES_MakeCurrent()" function) that was causing a crash when exiting SDL. There was a problem while terminating the x11 egl window, that was preventing to quit/close SDL/SDL-window then reload SDL/SDL-window inside the same application.
