John-Mark Allen 0cafc5c22d Consolodate to two non-generic renderers
There are now only two renderers (only generic over the GL context)
- `AutoRenderer` which is both the old `OwningRenderer` and also
  sets up a `SimpleTextureMap` automatically
- `Renderer` which borrows both the GL context and the texture map
  on every call to Render

This means the `RendererBuilder` can be entirely removed.

Also `TrivialTextureMap` renamed to `SimpleTextureMap`.
