2D renderer. The role of this class is to equip each style group with a specific renderer and to call these renderer to redraw the graph when needed. The renderers then equip each node, edge and sprite with a skeleton that gives is main geometry, then selects a shape according to the group style. The shape will be "applied" to each element to draw in the group. The shape will be moved and scaled according to the skeleton. A render pass begins by using the camera instance to set up the projection (allows to pass from graph units to pixels, make a rotation a zoom or a translation) and render each style group once for the shadows, and once for the real rendering in Z order. This class also handles a "selection" object that represents the current selection and renders it. The renderer uses a backend so that it can adapt to multiple rendering targets. As the shapes are finally responsible for drawing the graph, the backend is also responsible for the shape creation.
