- fixed issues with the refactoring of the recent commits. This one starts again.
- added builtins for TextureID.

Note about builtins: Currently they are just hacked into the compiler backend. They really should be made part of the respective types to keep matters clean and allow more widespread use of builtins to create more efficient code.
