All graphics library commands now take a gfx_context_t pointer, which points to a simple datastructure describing a rendering context (width, height, depth, total size, front buffer, backbuffer; where backbuffer = front buffer when not in double-buffering mode, thus we always render to backbuffer except on a flip). This may have caused a minor speed reduction, but I don't really care as it's far more important that we support multiple graphics contexts. TODO: - Shared Memory Fonts library (there are a couple of apps that use these so-called "shmem fonts" on their own; we need a dedicated library for them) - Break off "TTK" GUI toolkit into its own library. Since it's just a callback-based button framework, this shouldn't be too hard right now. Also, with the previous tick, I'll be able to put labels on controls and start using text in more places.
