Kevin Lange 4f2c122af5 Context-based graphics library.
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.
