	The fb_ops entrypoints and their descendants are purely readers of the settings, so constify their settings_t instances and the operative functions which only read settings.
2018-02-22	sdl_fb: implement rudimentary sdl fb backend	Vito Caputo
	This uses a simple fixed 640x480 windowed mode (for now). The SDL2 Renderer & Texture API is used for vsync-synchronized presents. There's probably excessive copying going on because the rototiller fb code manages pages and flips but SDL2 doesn't really expose low-level control of such things. This backend is quite useful for development purposes, allowing quick iteration in a windowed environment. Note this is just the backend implementation, it's dormant code but trivially activated.
