Draw all UI components with OpenGL.
Keeps UI component SDL_Surface for a smaller PR but avoids 4K penalty of uploading a 4K 32bit 33MB surface each frame 2GB per second. Only small component surfaces are uploaded each frame.
Splash, main menu and options screens are entirely OpenGL.
Replacing SDL_Surface in each component with OpenGL to be addressed in future PR.
Terrain editor Surf_Map remains 2D/SDL/SGE in this branch.
