User interface API

---

Detailed Description

These classes provide a simple 2D graphical user interface (GUI). The drawing is layered on top of the OpenGL renderer and using the input functionality of the context singleton, so the environment must be set up before the user interface can be drawn.

The user interface classes make heavy use of signals, and its design is in many ways similar to the gtkmm library. One notable difference is that, since we are working on top of OpenGL, usually together with 3D rendering, we need to redraw the entire interface each frame.
